Polygenic Inheritance Problem
Capital M = melanin, darker skin color
Capital N = no melanin, lighter skin color
Imagine the following couple:
MN MN MN (female) x MN MN MN (male)
Give the phenotypes for these parents.
Female:
Male:
I. What is the genotype of the darkest child they could have?
II. What are the odds of producing such a child?
III. What is the genotype of the lightest child they could have?
IV. What are the odds of producing such a child?
V. What are the odds of having a child that is heterozygous for all three genes?
