WebMeiosis and fertilization create genetic variation by making new combinations of gene variants (alleles). In some cases, these new combinations may make an organism more or less fit (able to survive and reproduce), thus providing the raw material for natural selection.

Web16 sep. 2024 · Fertilization triggers continuation of meiosis II, resulting in a two-pronuclear pre-embryo displaying two polar bodies and pronucleus (B). What is the relationship between meiosis and fertilization? Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote. WebMeiosis is the process in sexually reproducing eukaryotes that forms sex cells or gametes, which include sperm and eggs (ova). To avoid doubling the number of chromosomes in each generation, reduction division (halving the number of chromosomes) in gamete production is necessary. Chromosomes are typically diploid (2N) or occur as double sets ...
