Meiosis

Vedclass · Answer

(A) Meiosis is the process of cell division that results in the formation of four haploid daughter cells,each with half the number of chromosomes as the parent cell. During meiosis,specifically in Prophase-$I$,genetic recombination (crossing over) occurs between homologous chromosomes. This process introduces genetic variation in the offspring,which is the raw material for evolution and natural selection. Therefore,meiosis is considered significant for evolution.
