law

 [law]
a uniform or constant fact or principle. For specific named laws, see under the name.
law of independent assortment the members of gene pairs segregate independently during meiosis; see also mendel's laws.
inverse square law the intensity of radiation is inversely proportional to the square of the distance from the source of radiation.
law of segregation in each generation the ratio of (a) pure dominants, (b) dominants giving descendants in the proportion of three dominants to one recessive, and (c) pure recessives is 1:2:1. This ratio follows from the fact that the two alleles of a gene cannot be a part of a single gamete, but must segregate to different gametes. See also mendel's laws.

law of seg·re·ga·tion

factors that affect development retain their individuality from generation to generation, do not become contaminated when mixed in a hybrid, and become sorted out from one another when the next generation of gametes is formed.
Synonym(s): Mendel first law

Mendel,

Gregor Johann, Austrian geneticist, 1822-1884.
Mendel first law - factors that affect development retain their individuality from generation to generation, do not become contaminated when mixed in a hybrid, and become sorted out from one another when the next generation of gametes is formed. Synonym(s): law of segregation
Mendel second law - different hereditary factors assort independently when the gametes are formed. Synonym(s): law of independent assortment
mendelian character - an inherited character under the control of a single locus.
mendelian inheritance - inheritance in which stable and undecomposable characters controlled by a single genetic locus are transmitted over many generations. Synonym(s): alternative inheritance
mendelian ratio - the ratio of progeny with a particular phenotype or genotype expected in accordance with Mendel law among the offspring of matings specified as to genotype or phenotype.
