Vedclass · Answer

(B) Meiosis contributes to evolution primarily through the generation of genetic variation.During meiosis,processes like crossing over (recombination) and independent assortment of chromosomes create new combinations of genes in gametes.These genetic variations are essential for natural selection,which drives the process of evolution.Furthermore,while meiosis reduces the chromosome number by half,it ensures that the species-specific chromosome number is maintained across generations through fertilization.
