2.Can the student tell from blood type if the student is heterozygous or homozygous? describe.

3.Select a trait of interest.

A.What was the trait?

B.What is the phenotype for the trait, and is this the dominant or recessive allele for the trait?

C.What are the possible genotypes for the parents?

D.Include the results of one Punnett square, showing a possible combination between alleles for the trait from the parents by filling in the genotypes according to the numbers in the square, below. (Note: you do not need to submit the punnett square itself, only the results of the punnett square).

1 2
3 5 6
4 7 8

E.Based on the cross, what percent of children born to the parents would express the trait?

B.What is the probability of males having hemophilia out of the entire population?

C.How many females would have hemophilia?

D.How many carriers would there be?

12.describe why more males tend to suffer from X-linked disorders than females.
