In experimental genetics, matings were given specific names depending on the genotypes of the mates.

Parents : P1(AA) x P2(aa) F1 generation (FilialGeneration no.1) :

if, the mating is

• F1 x F1 : Intercross F1 x P1 or F1 x P2 : Backcross

2개 이상의 locus를 이용하여 mating을 하여, P : AABB x aabb F1 : AaBb 일때,

• AaBb x AaBb : DoubleBackcross AaBb x AABB (or aabb) : DoubleIntercross
