Mendel's Law Definition

One of two principles of heredity first formulated by Gregor Mendel, founded on his experiments with pea plants and stating that the members of a pair of homologous chromosomes segregate during meiosis and are distributed to different gametes.

The second of these two principles, stating that each member of a pair of homologous chromosomes segregates during meiosis independently of the members of other pairs, with the result that alleles carried on different chromosomes are distributed randomly to the gametes.
