Which statement describes Mendel's Law of Segregation?

Explanation:
Alleles for a gene separate into gametes so that offspring inherit one allele from each parent. This is Mendel's Law of Segregation: during meiosis, alleles at a gene separate so each gamete carries a single allele, and fertilization restores the pair. For a heterozygote (Aa), the gametes contain A or a with equal probability, producing a 1:2:1 genotype ratio and, with complete dominance, a 3:1 phenotype ratio in offspring from Aa x Aa. The statement that captures this idea is the Law of Segregation itself. Other options refer to different principles: independent assortment describes how separate genes assort independently; dominance describes how phenotypes are expressed; blending inheritance is an outdated idea about trait blending.
