Question

Why is sexual reproduction important to the process of natural selection?

Answer 1

Sexual reproduction is a type of reproduction. It involves a complex life cycle in which a gamete with a single set of chromosomes combines with another gamete from each parent to produce a zygote. This zygote develops into an organism composed of cells with two sets of chromosomes. This organism is genetically different from its parent organisms.

Complete Answer:
Sexual reproduction can produce the possibility for natural selection to choose from hundreds of thousands of variations.
It is estimated that there are more than 30,000 genes in the human genome. There are a wide number of possible combinations of these genes in sexual reproduction.
Natural selection can’t produce information. It can only choose the information best suited or adapted to a particular environment by eliminating and causing the disappearance of those variants that are less well adapted.
Sexual reproduction provides an immeasurable selection of variants for Natural Selection to choose from. We can just think about all the variants of humans on the planet, some people are suited to some environments better than other variants.
The genome of the grey wolf has given birth to a wide array of dog breeds. Artificial selection has chosen different variants of the genome eliminating some parts to create all the different varieties of dogs that still belong to the same species.

Note:
The change in inherited characteristics in a population of organisms over many generations is called Evolution. The process that best explains evolution is a phenomenon known as natural selection. Natural selection is the process by which certain inherited characteristics like the height of a person, colour of a fish or the shape of a leaf are favoured within a population. A population is a group of organisms that mate with each other and reproduce another organism.
