Detailed explanation-1: -Meiosis also differs from mitosis in that it involves a process known as recombination, during which chromosomes exchange segments with one another. As a result, the gametes produced during meiosis are genetically unique.

Detailed explanation-2: -Chromosomal crossover involves recombination between the paired chromosomes inherited from each of one’s parents, generally occurring during meiosis.

Detailed explanation-3: -The unique combination of alleles that all sexually reproducing organisms receive from their parents is the direct result of recombination during meiosis.

Detailed explanation-4: -Answer and Explanation: Genetic recombination refers to the process by which the cells acquire a genetic constitution different from that of the parent cell. In this sense, fertilization is a form of genetic recombination. During fertilization, the male and female gametes fuse to form a zygote.

Detailed explanation-5: -Homologous Recombination During the formation of egg and sperm cells (meiosis), paired chromosomes from the male and female parents align so that similar DNA sequences can cross over, or be exchanged, from one chromosome to the other.
