During meiosis, a diploid produces gametes that are haploid in character. This means that although a diploid individual has two copies for each gene, possibly having two different alleles for the given gene, only one copy is to be passed on to their offspring. Such is the case that happened in the individual's parents, as they pass it on to their offspring.
The A and B genes are on nonhomologous chromosomes. A zygote is formed by the fusion of a sperm with genotype AB and an egg with the genotype ab. The zygote develops into a male. Which of the following are genotypes of sperm that could be produced by this male?
A. AB and ab only
B. AB, ab, Ab, and aB
C. only AB
D. only ab
E. aB and Ab only
