Answer
The offspring will not have the DD genotype.
Solution
a
The male has the genotype DD, meaning he has two dominant alleles
b
The female has the genotype dd, meaning she has two recessive alleles
c
When they crossbreed, each parent contributes one allele to the offspring
d
The possible combinations of alleles for the offspring are Dd
Key Concept
Genotype inheritance
Explanation
When a male with genotype DD and a female with genotype dd crossbreed, the offspring will inherit one dominant allele (D) from the male and one recessive allele (d) from the female, resulting in the genotype Dd. Therefore, it is not possible for the offspring to have the DD genotype.
