Germ cells are localised in the gonads of plants and animals alike. ![]() Meiosis occurs in the germ cells of organisms that reproduce sexually. Meiosis is a specialized form of cell division in sexually reproducing organisms that results in four non-identical haploid cells (gametes) from a single diploid parent cell, ensuring genetic diversity and maintaining consistent chromosome numbers across generations. Its intricate steps, from recombination to the reductional division, underscore its significance in reproduction, evolution, and genetic health. In conclusion, meiosis is a fundamental biological process that ensures genetic diversity and the stability of chromosome numbers across generations. ![]() Errors during meiosis, such as non-disjunction where chromosomes fail to separate correctly, can lead to conditions like Down syndrome, where an individual has an extra chromosome 21.
