Question

10) Somatic cells of Drosophila simulans have a diploid chromosome number of 8. Drosophila are unusual among animals in that crossing over during meiosis does not occur in males. What is the probability that a sperm cell from a male contains replicas of only those chromosomes the male received from his female parent?

Answer 1

Answer:

Meiosis from a diploid cell comprises four genetically distinct chromosomes (egg cells or sperm cells). A diploid cell contains an entire collection of chromosomal pairs. That pair contains a single parent chromosome. These chromosome pairs are not the same or are homologous (equivalent) clusters, as they contain numerous gene loci.
