A woman of blood type A and normal color vision produced five children as follows:

a)male, blood type A, color blind
b)male, blood type O, color blind
c)female, type A, color blind
d)female, type B, normal vision
e)female, type A, normal vision

of the two men that mated with this woman at different times, man #1 is blood type AB and color blind, while man #2 is blood type A and normal.
for each child, which of the men is the most probable father? (color blindness is an X-linked recessive allele, and that the blood type alleles Ia, Ib, and i are autosomal.

#### Solution Preview

Ia- type A Ib- type B i- type O
C- normal vision c-colorblind

Mother's possible genotpyes
blood type Ia, Ia or Ia, i
colorblindness C, C or C, c

Man #1's possible genotypes
blood type Ia, Ib
colorblindness c, - (because this is x-linked he only has one allele)

Man #2's possible genotypes
blood type Ia, Ia or Ia, i
colorblindness ...

#### Solution Summary

The probability of a women of blood type A and having normal color visions are determined. Possible genotypes are analyzed.
