Detailed explanation-1: -Genetic recombination is a process of exchange of genetic material between different organisms to produce offspring with new combination of alleles. Fertilization is a process of fusion of the male gamete with the female gamete to form a zygote. During meiosis, genetic variations result in genetic recombination.

Detailed explanation-2: -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-3: -So, the correct answer is ‘Fertilisation and meiosis’

Detailed explanation-4: -Recombination Occurs During Meiosis of Higher Organisms In mitosis, recombination serves to repair double-stranded breaks or single-stranded gaps in the chromosomes.
