Sexual reproduction is most advantageous , due to genetic variation . Meiosis plays an important part in sexual reproduction. During meioisis , after synapsis , genetic recombination occurs , dure to which we get varied gene pairs as well parental strands too .
Reproduction is the process of generating offspring. There are two main types of reproduction: sexual and asexual. Some organisms reproduce by only one type of reproduction and others can reproduce by both.This chapter looks at the differences, advantages and disadvantages of sexual and asexual reproduction.he type of reproduction where cells from only one parent are used, is called asexual.
