The law of segregation states that alleles for the same trait separate during gamete formation. This foundational principle of genetics, proposed by Gregor Mendel, explains how the two alleles for a gene (one inherited from each parent) segregate from each other when gametes (sperm and egg) are formed. As a result, each gamete carries only one allele for each gene, ensuring that, during fertilization, the offspring receive one allele from each parent, restoring the pair. This segregation occurs during meiosis, the process of cell division that produces gametes, making it possible to predict inheritance patterns of traits based on the alleles carried by the parents.

The other options present different concepts related to genetics but do not accurately describe the law of segregation. The law of independent assortment, for instance, refers to how different genes independently separate from one another when forming gametes, which is a separate concept from the segregation of alleles for the same trait. The idea of dominance, where one trait can mask another, aligns more closely with how certain alleles can overshadow others rather than the separation of alleles during gamete formation. Lastly, the fixed patterns of inheritance relate to broader principles of inheritance rather than specifically addressing the segregation of alle
