WebApr 11, 2024 · We can think of meiosis as a way cells very carefully count and divide their chromosomes so that each gamete, each egg or sperm, has exactly 23 chromosomes. Then when an egg with its 23 chromosomes is fertilized by a sperm with its 23 chromosomes, the resulting fertilized egg has exactly 46 chromosomes. WebAnswer (1 of 2): In the gonads i.e. the ovaries of the female of the species, and testes of the male. These are the organs in which gametogenesis (sex cell/gamete formation) occurs. …

Meiosis - Definition, Stages, Function and Purpose

WebHumans have 23 chromosome pairs, which results in over eight million (2 23) possibilities. This number does not include the variability previously created in the sister chromatids by crossover. Given these two mechanisms, it is highly unlikely that any two haploid cells resulting from meiosis will have the same genetic composition ( Figure 7.4 ). http://www.differencebetween.info/difference-between-meiosis-in-plant-and-animal-cells church of saint benedict mohnton pa
