Offspring are different from their parents due to genetic recombination, crossing over, and random chromosome assortment.

Offspring are different from their parents due to three processes: genetic recombination, crossing over, and random chromosome assortment.

Genetic recombination occurs when chromosomes exchange genetic material during gamete formation, creating new combinations of genes.
Crossing over is when homologous chromosomes exchange segments of DNA during meiosis, leading to the formation of genetically different gametes.
Random chromosome assortment occurs during meiosis when homologous chromosomes line up randomly, causing different combinations of maternal and paternal chromosomes in the resulting gametes.
