WebGenetic variation will only slowly be restored through the accumulation of mutations over many generations. For this reason, an endangered species with low genetic variation may risk extinction long after its population size has recovered. Genetic variation doesn’t rebound from a decrease as quickly as population size. WebThe primary result of mitosis and cytokinesis is the transfer of a parent cell's genome into two daughter cells. The genome is composed of a number of chromosomes—complexes of tightly coiled DNA that contain genetic … Webpotentially resulting in genetic mutations that can lead to a variety of diseases, including malignancy.
