Mendelian genetics artificial selection is the purposful mating for domesticating plants and animals. Dogs are domesticated wolves, bred for seelcted traits belyaev fox study russian scientist did experiment on fox domestication corn is also very domesticated. Gregor mendel: austrian monk and expert plant breeder garden peas: are easy to work with because it is easy too cross fertilixe and there is a large nimberof offspring and the growing season is short. He found a consistant pattern of inheritancce from which he based his theories. Prior to mendel: there were theories that one parent contributes more than the otehr which was disproved via reciprocal crosses parential traits become mixed and forever changed in the offspring, disproved through reapperances of recessive traits. Monohybrid crosses are matings between individuals that only differ in one trait. All f1 progeny resembled one of the parental strains in f2 the progeny, lost trait reappears. Discrete units of inheritance are allels of genes.
