What is asexual reproduction and sexual reproduction?

Asexual reproduction (agamogenesis) is a method of reproduction in which offspring appears without the help of germ cells. Evolutionarily arose earlier than sexual reproduction. With this type, the old and new individuals are identical, they are a copy (the gene set is also unchanged). Also, only one parent is involved in the birth of new “children”. At the same time, many offspring appear. Various microorganisms, fungi, plants and some species of invertebrates spread by this type.
During sexual reproduction, two progenitors are involved, due to the fusion of genes (the offspring has an individual gene set. Automatically, an individual is not born a copy. This method reproduces most of the plants and animals.
