NEET BIOLOGY

Detailed explanation-1: -It is one of the final phases of genetic recombination, which occurs in the pachytene stage of prophase I of meiosis during a process called synapsis.

Detailed explanation-2: -Complete answer: Genetic recombination occurs in the Pachytene phase of prophase of meiosis I. So, the correct option is (C). Meiosis-It occurs in the mature diploid reproductive cells in which the nucleus divides twice but the chromosome replicates only once to form four haploid cells.

Detailed explanation-3: -Recombination in meiosis. Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.

Detailed explanation-4: -Between prophase I and metaphase I, the pairs of homologous chromosome form tetrads. Within the tetrad, any pair of chromatid arms can overlap and fuse in a process called crossing-over or recombination. Recombination is a process that breaks, recombines and rejoins sections of DNA to produce new combinations of genes.
