Vedclass · Answer

(D) Meiosis is a specialized type of cell division that reduces the chromosome number by half,creating four haploid cells. Its significance for evolution lies in the process of genetic recombination (crossing over) that occurs during Prophase-$I$. This process shuffles the genetic material between homologous chromosomes,leading to variations in the offspring. These variations are the raw material for natural selection and evolution. While options $B$ and $C$ describe outcomes of meiosis,they do not directly explain the significance regarding evolution as effectively as genetic recombination does.

Meiosis is significant for evolution because it results in:
