When number of chromosomes is already reduced to half in the first reductional division of meiosis. What is the necessity of second mitotic division?
the division is required for the formation of four gametes
division ensuress equal distribution of haploid chromosomes
division ensures equal distribution of genes on chromosomes
division is required for segregation of replicated, chromosomes
Meiosis is reductional division where as, meiosis II is equational division due to
