Here's why:
* Homologous chromosomes: These are chromosome pairs, one from each parent, that carry genes for the same traits.
* Meiosis: This is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell.
* Independent assortment: During meiosis I, homologous chromosomes pair up and then separate randomly into different daughter cells. This means that each daughter cell receives a mix of maternal and paternal chromosomes, and the specific combination is random.
This random segregation of chromosomes is a major source of genetic variation, contributing to the diversity of offspring.
