9. In human beings, the gene for red-green colorblindness (r) is sex-linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal-visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. a. What is the genotype of the woman's father? b. What is the probability that the couple's first child will be a non-freckled, normal visioned girl c. What is the probability that the first two children born to the couple will be freckled and colorblind girls? d What ic the

9. In human beings, the gene for red-green colorblindness (r) is sex-linked and
recessive to its allele for normal vision (R), while the gene for freckles (F) is
autosomal and dominant over its allele for nonfreckled (f). A nonfreckled,
normal-visioned woman whose father was freckled and colorblind, marries a
freckled, colorblind man whose mother was nonfreckled.
a. What is the genotype of the woman's father?
b. What is the probability that the couple's first child will be a non-freckled,
normal visioned girl
c. What is the probability that the first two children born to the couple will
be freckled and colorblind girls?
d. What is the probability that the first child born to the couple will either be
a freckled, colorblind boy or a non-freckled, normal visioned girl or a
non-freckled, normal visioned boy
e. What is the probability that the first four children born to the couple will
be freckled and normal visioned girls?
