Question

Assume that a dihybrid cross is made in which the genes' loci are autosomal, independently assorting, and incompletely dominant. How many different phenotypes are expected in the offspring?

Answer 1

The different phenotypes expected are 1:2:1:2:4:2:1:2:1

Explanation:

Cross between AbBb X AbBb

F1 generation : AbBb

Zygotes – AB , Ab , aB , ab

F2 generation:

Genotype of the individuals from the cross = 1:2:1:2:4:2:1:2:1
