Random mating
Explanation:
Random mating is a type of mating that allows individual to have equal chance of been mated to.
AA genotye is mated with aa from a population and they produce
Four individuals with Aa
AA × aa
!
F1: Aa Aa Aa Aa
This individuals then intermate in the next generation to produce an offspring with three difference genotype AA, Aa, aa in ratio 1:2:1 this is called segregation of genes. This allow to see the variation and hidden features of the individual mated.
Aa × Aa
!
AA Aa Aa aa
F2: 1/4 AA, 1/2 Aa, 1/4 aa
