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.
<h3>What are
gametes?</h3>
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.
