Mendel's Law of Segregation describes which process?

Alleles separate into gametes during meiosis so each gamete carries a single allele for a given gene. When fertilization occurs, offspring receive one allele from each parent, restoring two alleles in the zygote. This explains why recessive traits can reappear in the next generation and underlies the typical 3:1 phenotypic ratio seen in a monohybrid cross of heterozygotes (Aa x Aa yields 1 AA, 2 Aa, 1 aa). This is distinct from independent assortment, which describes how alleles of different genes sort independently.
