segregation defined in 1951 yearsegregation - segregation;
segregation - Separation into different gametes, and thence into different offspring, of the two members of any pair of allelomorphs possessed by an individual; the two allelomorphs having previously been brought together in the individual, one from each of its parents; and having in no way blended or altered each other while associated together in the individual. What is known as Mendel's first law asserts that allelomorphs segregate. Segregation is the result of the relatively unchanging nature of genes; of their separate carriage in chromosomes; of the mechanism of meiosis which provides each gamete with only one member of each pair of chromosomes; and of fertilization by which pairs of chromosomes are formed again.
