At the beggining of class we went over our homework. We spoke in our groups about what the questions last night were about. Our group said that the questions were meant to make us think about where our traits came from. Mr. Finley then asked us about where our traits came from and which parent gave them to us. We figured out that our parents somehow give us all of our genes. We then continued playing our pea soup game. We had to continue coming up with predictions and try to get 5 correct predictions in a row. Our group didn't come up with the right hypothesis. We only got a couple of correct outcomes. Jordan was the only person in the class that fully understood the simulation.
Hello it's Jordan..............................
ReplyDeleteA way to find out the four children peas based on two parent peas is that first do not worry about the Yy or RR. Just worry about color and appearence. First take the parent who has less kids look like him than the other. Next identify that characteristic that makes him less like the rest of his family. This gene will be recessive, and one out of four of the children will have that characteristic. If any of the parents have smoothness then two out of three of the remaining child peas will be smooth, and there will be one wrinkly pea. I say this because in the simulation smoothness seemed to be a very dominant gene. Now how to tell the color.....
Green seem to be the dominant gene in the simulation so if one parent is green and one parent is yellow here is how you'd crack the code...first you would have to look back further and look at the parents of the current parents. If they were both yellow then the children of the current parents will have one green and three yellow peas. If the grand parents are both green then there will be three green children and one yellow child pea. Heres the tricky part if one grandparent is yellow and the other is green there will be three green baby peas, and one baby yellow pea because as I said green is the dominant color. Now what if both parents are green? If both parents are green then you have to look at the grandparents. If those grandparents are both green then all of the baby peas will be green. If the grandparents are one yellow and one green then there will be three baby reen peas, and one baby yellow peas.
Finally what if both of the parents are yellow?
Well you do the same thing for two yellows as you do for two green parents. I know this is long and hard to understand and I apologize for that.
its true the color of the pea depends on the parents and other ancestors as the same with it being smooth or wrinkly. The dominant gene for color is usually in the majority of children

ReplyDeleteWhat I don't understand is why those letters are there that really confuses me, but i do understand what Jordan is sayin
I'm not sure if green is the dominate color... When I did the experiment, I had yellow a lot. I think that if you start will all yellow or all green, the children will be all yellow or all green. Also if the starting parents are all wrinkly or all smooth, the children will be the same.
ReplyDeleteWell, I think that if the parents are different, let's just say one yellow and one green, then there will be 2 yellow children and 2 green. Then if you take 2 of the green peas, there will be 3 green and one yellow. I think thats because there is 1/4 chance that the pea will be yellow. It's like if your grandmother is 100% German, then your mom/dad will be 50% German, and you will be 25% German. That works for wrinkly and smooth peas too.
I don't get the letters though. They seem to be switched. I started with 2 peas. One was YY and Rr and the other was YY and RR. The children all had YY, but 2 had RR and the other 2 had rR. Then when I breeded one of the RR ones and one rR, 2 of the children had Rr and the other 2 had RR. The letters seem to get switched every time.

I agree with Jordan, green is dominant...I had 2 green parents and 1 green 1 yellow grandparents, the children were all green when they should have been 3 green and 1 yellow. I also think that there may be a way to figure out the way the children will come out with the letters but I still have to test which letters in which order= the color of the pea and whether its round or wrinkled...but basically you take the first letter of the first parent and that's the first letter of the children, then the 1st letter from the other parent is the other letter. You do this for both r and y. The sequence of letters creates the traits of the children. I think this is something like the chromosomes that the parents give.

I agree with Sophie because i worked with her and all day yesterday we got yellow peas and today we finnaly got green peas.I think the letters under the peas were the pea's genetic code or something like that.
ReplyDeleteSambavi
In addition to what I said before I realize now that r and y are the homologus pairs, that explains why the peas get the first letter from 1 parent and the other from the other parent. As we know homologus pairs determine our traits...the reason we take the first letter is because the second is the recessive chromosome.
ReplyDeleteIW
i sort of agree with jordan. this is the stuff i came up with: you might have one trait thats dominant, but there could be a trait from your grandparents that you have, but it's not dominant, but maybe in a future generation, someone may have that trait as a dominant trait. that happened a lot with the pea soup experiment. there would be two yellow and wrinkly peas, and the children would have three of them identical to the parents and one that was green and smooth. there was a green and smooth pea from 2 generations ago, which we thought was a recessive trait.

I found out that if you multiply the number of lets just say capital R's in both parents combined by 2, the answer would be the amount of that trait in the children combined. You would multiply it by 2 because there were 2 parents and 4 children and 2 times 2 equals 4. So if there were 3 capital R's in the parents combined, then in the mix of the children, there will be 6 capital R's no matter what. Same thing goes for all the other letters lowercase and upper.But the arrangement of the traits will vary because of the dominance of the trait. I found out that yellow is the most dominant color because only 2 lowercase y's make green while 2 uppercase and an uppercase and lowercase together can make yellow. Therefore I believe that Jordan's prediction is correct because there would in fact be 1 green and 3 yellow children if there was at least 1 lowercase y in at least 1 of the parents. Except I think that Jordan mixed the yellow and the green up by accident.

I agree with Joradan and Ivan. I think that two lowercase yy means that its is green. I do because whwen ever i got a green pea it was yy. I can't seem to figure out how the letters change. I belive that the children peas are the same uppercase or lowercase of the Parent's just in a wierd order. I am still trying to find out how.

PARENTS:

Rr
CHILDREN:
yy

--------------------------------------------------------------------------------
yY
rr
--------------------------------------------------------------------------------
Yy
rR
--------------------------------------------------------------------------------

Notice that there were 2 lowercase y's in the parents combined and 4 lowercase y's in the children combined. 2x2=4
Notice that there were 2 uppercase Y's in the parents combined and 4 uppercase Y's in the children combined. 2x2=4
Notice that there were 3 lowercase r's in the parents combined and 6 lowercase r's in the children combined. 3x2=6
Notice that there was 1 uppercase R in the parents combined and 2 uppercase R's in the children combined. 1x2=2

I also agree with Jimmy about two uppercase YY mean its yellow. Also two lowercase rr mean that is is wrinkly. Also is there is at least one uppercase R it means that it is round.
ReplyDeleteJohnny S
But green can't be dominant if the only combination can be yy while yellow can have 2 combinations of yY or YY. Therefore yellow has to be dominant because it has more possibilities.
ReplyDelete-Jimmy Evangelos
I worked with Jake Vignali and we got mostly yellow and yellow wrinkly so i dont think that green is the dominant color unless you start out with a parent pea being green. I think that the dominant color of you children peas depend on what color the parents are. I do think that the letters under each parent cell has to do with color also though.
ReplyDeletePH
I believe that the y's lowercase and uppercase represent the color and that the r's lowercase and uppercase represent the texture.
ReplyDeleteSorry, the comment I just made was mine. Jimmy Evangelos. The comment that I didn't put my name on said that I posted it at 2:37 which makes no sense because it's 5:37 but wutevr.
ReplyDelete-Jimmy Evangelos
Disregard what I said earlier I messed up one thing. If you did what I did the children would all have the same letters. What you have to do is take the first letters for both r and y of each parent. These are the letters for the first 2 children. The second two get the other letters. This way all the children are different.
ReplyDeleteIW
I think that the pea soup experiment was like what happens in real life to humans. You get most of your traits from your parents but some that sort of aren't from your parents because they don't have it but, are really from your parents because they passed down the recessive gene. But, your parents got the gene from your grandparents but it was recessive gene not dominate as in your grandparent. This answers the question of how you get trait that your parents don't have.
ReplyDeleteTG
The capital letter is the dominant trait. If it is Yy thenit will be yellow. The only way the pea will be green is if the letters are yy. Yelow is the dominant color and round is the dominant texture.
ReplyDeleteSean Cole
I agree with Jordan and the fact that green is the dominant trait...But now I am confused when Jordan said "If the grandparents are one yellow and one green then there will be three baby reen peas, and one baby yellow peas." Also, is there another way in order to figure out the recesive trait and what color the baby peas will be... If so, can someone please explain to me how to do it?
ReplyDeleteLorik Berisha
I worked with Natalie so I agree with her. You may have a trait that is dominant which makes you look a certin way, but you could also have another trait in you that isn't dominant but you could still pass it on to your kids. The trait could skip a generation or two and end up in your grandchildren. We noticed that a lot in the experiment, many times we would have 2 yellow and smooth parent peas and 3 of their children would be identical to the parents, but there would usually be at least 1 child that was green and wrinkled. We thought the one that was green and wrinkled was different because one of the granparent peas was green and wrinkled and the parents could still passed it down to them.
ReplyDelete-Rachel Turrisi
I believe that Rachel is correct that the trait that's not dominant (recessive trait) is passed down a few generations and might not be visible in the parents, but the grandparents or great grandparents. Your parents still have the trait even though it's not visible.
