Drosophila has a diploid chromosome number of 2n=8, which includes one pair of sex chromosomes (XX in females and XY in males) and three pairs of autosomes.Consider a Drosophila male that has a copy of the A1 allele on its X chromosome (the Ychromosome is the homolog) and is heterozygous for alleles B1 and B2, C1 and C2, and D1 and D2 of genes that are each on a different autosomal pair. For the questions that follow, assume that no crossovers occur between homologous chromosomes.

Explanation / Answer
Dear Candidate
The Ans. of your question is following as -;
(1) Part A
The ANS. of your question is A1A2B1B2C1C2D1D2, because Mitosis produces cells with the same starting genotype
(2) Part B
The Ans. is 4
(3) Part C
The Ans. is 16 Genetically different gametes
