Question

List and briefly describe the three processes that lead to variation in offspring with the same parents.

Answer 1

The answer to the question is-

a. Non-sister homologous chromosomal crossover happens in prophase I. New gene combinations are created as a result of DNA segment exchanges between maternally derived and paternally derived chromosomes.

b. Gametes with a mixture of maternal and paternal chromosomes are produced as a result of random alignment during metaphase I.

c. Fertilization is unpredictable since any two gametes can mate.

What are gametes?

In sexually reproducing species, the haploid cell known as a gamete is fused with another haploid cell during fertilization. The reproductive or sex cells of an organism are known as gametes. A female is any individual that generates the larger kind of gamete, known as an ovum, and a male is any individual that produces the smaller type, known as a sperm, in species where each individual produces just one type of gamete.
