How does fertilization lead to variation
WebFertilization is a process that involves the fusion of two haploid gametes, one from the male and the other from the female, resulting in the formation of a diploid cell called a zygote. Therefore, fertilization results in a diploid cell. The zygote contains a complete set of chromosomes, half from each parent, which provides the genetic ... Web33. Meiosis and sexual reproduction each lead to variation in the genetic make-up of every person. With your group, explain how meiotic events, as well as the random fertilization of eggs and sperm, together lead to this genetic variation.
