BIO DD
->For all problems, show your complete soultions [including all parental genotypes, GR and PR (if applicable)]. Write down all possible answers.
1. A husband and wife have normal vision, although both of their fathers are red-green colorblind, which is inherited as an X-linked recessive condition. What is the probability that their first child will be:
a) normal son?
b) normal daughter?
c) colorblind son?
d) colorblind daughter?
2. In cats, yellow coat color is determined by the b allele and black coat color by the B allele. The heterozygous condition results in a color known as tortoise-shell. These genes are X-linked.
a) What kind of offspring (and in what ratio) would be expected from a cross of black male and a tortoise-shell female?
b) What would be the chances of getting a tortoise-shell male?
3. A couple are both phenotypically normal but their son suffers from hemophilia, a sex-linked recessive disorder.
a) What fraction of their children are likely to suffer from hemophilia?
b) What fraction of their children are likely to be carriers?
4. In fruit flies, an X-linked dominant allele produces red eyes while its recessive counterpart gives them white eyes.
a) If a white eyed male reproduces with a homozygous red-eyed female, what phenotypic ratio is expected from their offspring?
b) If a white-eyed female reproduces with a red-eyed male, what phenotypic ratio is expected from their offspring?
