Genetic drift is such type of mutation that may become more common in the population and over time due to the process
Genetic drift is describes as the random fluctuations in the numbers of the gene variants in a population. Genetic drift may takes place when the occurrence of the variant forms of the gene, called as alleles, increases and also decreases by chance over time. These variations is the presence of alleles are to be measured as the changes in allele frequencies. In the population, the different of alleles that create the coat color are equally distributed. for example A disease which comes into the rabbit population and kills the 98 of the rabbits. The only rabbits that are is left are red and grey rabbits, simply by the chance. The genes have thus called “drifted” from 6 alleles to only 2.

Only eukaryotic organisms, or those whose cells contain nuclei, undergo mitosis.Our body cells are somatic cells(skin,cheek,stomach cells). These cells must go through mitosis to maintain daily functions of the cells like growth and repairing damaged tissue.
