Pea Soup!
First Mr. Finley told us we had to write a paper connecting genetics with meiosos and mitosis that has 12 font, double spaced, and is 1 page. It has to be double spaced. We then started talking about the Pea Soup! experiment. We didn't do a great job identifying patterns and similarites and differences we have already seen. Some were that all the green peas had yy letters and the yellows had Yy and YY. The yellow peas have atleast 1 uppercase Y. All the round peas had atleast 1 uppercase R. This means its round. Evidence its only 1 is the parent has 2 RR and the children are rR and they are all round. We chose to have a yellow pea thats round by itself. The children of it should have 3 yellow peas and 1 green pea. 3 will be round, and 1 will be wrinkled. We ended up with 2 yellow round, 1 yellow wrinkled, and 1 green round. We then discussed how to be able to predict transmission. Since 50% of chromosomes come from the parent and 50% come from the other parent. The method to figure out colors are that the first child gets the first Y's from the first ys of the parents. The second child gets the first Y from the first parent and second from the 2nd parent. The 3rd child gets its first letter from the 1st parents 2nd letter and 1st letter from the 2nd. The last child gets the 2nd letters from the parents. We figured out that the letters represebt chromosomes. To explain that 50% chromosomes come from each parent is that the egg and sperm are haploids. So you end up with 2 sperm with the first letter, 2 with the second. And the other 2 eggs with the first letter, 2 with the second.

The paper is only suppose to compare Mieosis and the Pea soup activity, homolgous pairs/Chromosomes and fertilization.
