List all the different gamete genotypes and the probability

List all the different gamete genotypes and the probability of observing each genotype that can be produced by an individual with the genotype AABbCcDd.

Solution

The different gamete genotypes formed will be : 2^ n = 2^3 =8 ( n= the number of heterozygotes i.e 3:Bb,Cc,Dd)

Gametes:

ABCD ,Abcd ,AbCd ,AbcD,ABcd ,ABcD,ABCd, AbCD

The probability of observing each genotype will be 1/8 = 0.125
