Genotypes

Today we started on class with Mr. Finley telling us that our class was a little behind the other classes. We continued our discussion from yesterday about talking about who could do the U shape with their tongue. In Jake Vignali's family, only him and his mother could do that. We figured out their genotypes were: Dad-cc Mom-Cc Jake-Cc Billie-cc JoJo-cc We figured that Jake would have one capital and one lower case c because he is a hybrid. This means that he only got this trait from his mother(capital C) and the didn't get this trait from his father(lower case c). Billie and JoJo both have lower case c's because the didn't get this trait at all. Together as a class we had made a punnet square of the Vignali's genotypes with the U shape tongue. In the punnet square, we didn't have any CC. We didn't have any because only one of the parents could make the U shape. We had to go over again what dominant and recessive meant. Dominant means that the specific trait overpowers the others. It is most visible. For example, in our class we could tell the U tongue shape because it is dominant in our class because everyone in our class could make the U shape besides one person. Recessive means that the specific trait is less visible and doesn't overpower the others. Some traits are genetically linked. An example that Mr. Finley gave us was that if your parents are good artists, they could pass the trait down. Also some genes block other genes from doing something. The most mutation is albinism. Albinism is the same as being Albino. A mutation in you means that all of the sudden in your life, a gene just changes. Heterozygous means they are different. Cc(genotypes) is considered a heterozygous because they are two different alleles. Examples of homozygous could be CC and cc. But cc is called homozygous recessive. CC is called homozygous dominant because capital C's means dominant. CC has two of the same alleles and same with cc. Now we have been given the challenge to make a punnet square of Ron and Herminees genotypes(Harry Potter characters). We ended class with Mr. Finley letting us know that we have a study session at 7 a.m. The picture shows you dominant and recessive alleles. In the attached picture, do not pay attention to the Gene Loci
