If a female with genotype Dd mates with a male of genotype d

If a female with genotype Dd mates with a male of genotype dd, what are the possible genotypes of the haploid gametes they produce?

Solution

If a female with genotype D//d mates with a male of genotype d//d, then we get the following :-

1) Female gametes would be haploid D/ and d/ types

2) Male gametes would be haploid d/ type only, as both autosomes would be assorted in a similar manner in the gametes.

Offsprings produced by the mating will have genotypes D//d and d//d, irrespective of sexes.
