Answer:

A.

Explanation:

To get the desired genotype, the breeder needs a BMMchromosome from one parent and a BRWchromosomefrom the other. Bug A has the BRWchromosome, and bug B has the BMMchromosome. Therefore, about one quarter of theoffspring of this pair will have the desired genotype. Bugs C and D have similar genotypes, but none will yield the exact allelecombination that is desired.
