Question

Using specific events in the formation of gametes and zygotes, describe why there is a greater diversity in sexual reproduction than in asexual reproduction.

Answer 1

In asexual reproduction only intervenes one progenitor and there are no specialized or sexual cells. This type of reproduction is frequent in unicellular organisms such as bacteria, alage, fungi; microorganisms like amoebas, and a lot of plants; offspring are identical to parents.
In sexual reproduction, specialized cells named gametes or sexual cells participate. Most of pluricellular organisms, female gametes are eggs and male gametes are spermatozoids; in plants, male gametes are polen grains.
Life beings with asexual reproduction propague rapidly and easily. Like when someone seeds a part of a plant (genarium stem or piece of cactus), in favourable conditions of humidity, light and nutrients, after a while a new plant will grow, with the same characteristics as the original one.
