In hardy Weinberg equation, the frequency of allele and genotype remains constant from one generation to another for a long period of succession. It only gets change when genetic disturbances such as genetic drift, mutation, natural selection, selective mating, founder's effect etc. comes in way.
However , the basic assumptions of Hardy Weinberg model is that there will be no genetic disturbance or gene flow in a given population and hence the frequency of alleles in a population that is in hardy-Weinberg equilibrium will be constant.
Answer: During mitosis a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
