Crossing over in germinal cells during gametogenesis is one of the primary causes of this variance. In humans, gametes are generated during meiosis, which reduces the chromosome number to 23.
One cell divides twice during meiosis to create four daughter cells. These four daughter cells are haploid, meaning they have half the amount of chromosomes as the parent cell. Meiosis generates sex cells or gametes? (eggs in females and sperm in males).
During meiosis, homologous chromosomes are paired, resulting in gene recombination.
Non-sister chromatids exchange genetic material, resulting in novel allele combinations.
