b. homozygous dominant.

c. homozygous recessive

d. none of these are correct

Answer #1

h h

H Hh Hh

h hh hh

So out of 4 offsprings half have dominant phenotype and half have recessive phenotype

therefore the genotype should Hh (Heterozygous)

so answer is a.

    A breed of dog (Mexican hairless) is completely hairless. There hairless dogs have heterozygous genotype "Hh". In contrast, normal, hairy dogs have the homozygous recessive genotype "hh". Puppy offspring that have the "HH" phenotype are aborted in utero, and still born. Matings between hairless dogs typically produce 10 offsprings. Given this information, how many hairless vs. hairy puppies would you expect in a typical mating between two hairless dogs.
