Carrier- Heterozygote that “carries” the affected allele, but does not express the allele (Allele remains hidden.)
** Who are the carriers?
Marian’s father is colorblind. Marian herself has normal color vision. Marian and her husband, Martin, who is also colorblind, have just had their first child; a son they have named Mickey. (Write the genotypes of Marian and Martin.)
a. What is the probability that their son is colorblind?
b. If Martin were not colorblind, how would this affect the prediction about Mickey?
c. If Marian and Martin were to have a girl, who they would name Minnie, what is the probability that she would be colorblind?
