Question

Compare the kind of variations introduced within a species that reproduces sexually with another species that reproduces asexually.

Answer 1

Variations in sexually reproducing species arise through the fusion of two dissimilar gametes, resulting in offspring with new gene combinations. This leads to genetic diversity through independent assortment, crossing over during meiosis, and random fertilization. In contrast, asexual reproduction produces offspring genetically identical to the parent, as it involves only mitotic division without gene mixing. Hence, sexual reproduction generates greater genetic variation, enhancing adaptability, while asexual reproduction results in uniform populations with minimal variation.
