Answer:
The correct answer is - 16 genetically different kinds of sperm could be produced by a Drosophila melanogaster male (XY).
Step-by-step explanation:
There are four pairs of chromosome in Drosophila melanogaster. In this species homologous chromosomes pair and segregate but do not follow recombination or crossing over. Each chromosome has two alleles or copies so as we know there are four pairs of chromosomes, then total number of chromosome copies would be 8, then
number of different combinations = 2^n (n = number of homologous pairs
)
2^n
= 2^4
= 16
Thus, the correct answer would be : 16.
