explain how sexual reproduction increases genetic diversity from one generation to the next. Specifically, describe how crossing over and random alignment in meiosis create genetic diversity. Then describe how fertilization increases genetic diversity.
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
explain how sexual reproduction increases genetic diversity from one generation to the next. Specifically, describe how crossing over and random alignment in meiosis create genetic diversity. Then describe how fertilization increases genetic diversity.
Sexual reproduction is a process whereby the the gametes produced by each parents combine together to form a zygote.
This process causes variation among individuals as the alleles produced by maternal and parental combine in the offspring. This sexual process though takes a longer time than asexual reproduction.
During the process there is homologous recombination where the specific segments of each chromatids gets exchanged by a process called crossing over.
This variation is very important as per the evolution because the sexual reproduction helps in the servival of the fittest one.
