Question

Whose theories are the basis for modern breeding techniques of plants and animals?

Answer 1

That would have to be the initial work of Gregor Mendel, the father of genetics.

Explanation:

Gregor Mendel was the first individual to scientifically show that during sexual reproduction, phenotypic traits are expressed in the progeny in mathematical ratios that are consistent with hybridization where one trait is dominant and the other is recessive. Reading about his experiments with the pea plants will give you better insight into his work.
