When a male pig from a line of true-breeding (homozygous) black, solid-hooved pigs was crossed to a female from
a breed (homozygous of red, cloven-hooved pigs, their several progeny all looked alike with regard to color and
hooves. these progeny were all mated to members of the same breed as their red, cloven-hooved mother pig. the
offspring from this final cross were: 11 black, cloven-hooved: 8 black solid-hooved: 14 red, clover hoved; and 10
red. solid-hooved. for each of these two genes (coat color and hoof type) determine which allele is the dominant
one. explain your reasoning. what were the phenotypes of the progeny produced by the first mating in this
problem?
