Assume sexual reproduction occurs. What is the number of chromosomes in the zygote if the parent's reproductive cells or gametes contain 12 chromosomes each

A) 6

B) 24

C) 48

The answer is B. This is because most species are dimorphic, meaning that they have two forms, male and female. Therefore, the formation of gametes is as a result of the union of two gametes from each morph. Gametes contain half the genetic material of the somatic cells of the individual parents. This way, the offspring will have half of each of the parent’s genetic material.
