Answer 1

Different types of gametes from Aa bb DD are AbD and abD.
number = 2

Different types of gametes from aa bb dd are abd
number = 1.

Genotype of offsprings: AabbDd and aabbDd.

Answer 2

A, B, D are three independently assorting genes with their recessive alleles a, b, d, respectively. A cross was made between individuals of Aa bb DD genotype with aa bb dd. 1. The type of genotypes of the offspring produced will be -

2. (a) AabbDd And

(b) aabbDd
