Mendel's law
noun
Men·del's law ˈmen-dᵊlz- 
1
: a principle in genetics: hereditary units occur in pairs that separate during gamete formation so that every gamete receives but one member of a pair
called also law of segregation
2
: a principle in genetics limited and modified by the subsequent discovery of the phenomenon of linkage: the different pairs of hereditary units are distributed to the gametes independently of each other, the gametes combine at random, and the various combinations of hereditary pairs occur in the zygotes according to the laws of chance
called also law of independent assortment
3
: a principle in genetics proved subsequently to be subject to many limitations: because one of each pair of hereditary units dominates the other in expression, characters are inherited alternatively on an all-or-nothing basis
called also law of dominance
