Detailed explanation-1: -The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually reproducing organisms alternate between haploid and diploid stages.

Detailed explanation-2: -During the process of gametogenesis, a germ cell undergoes meiosis to produce haploid cells that directly develop into gametes. Hence, in animals, meiosis is an integral part of gametogenesis.

Detailed explanation-3: -The meiotic cell cycle is common to both animals and plants gamete formation, but in animals the products of meiosis are gametes, whereas for most plants, subsequent mitotic cell cycles are needed for their formation.

Detailed explanation-4: -Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

Detailed explanation-5: -Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes in animals? During Meiosis, homologous chromosomes exchange genetic material.
