Question

2) In cattle, the hornless condition (H) is dominant to that for the possession of horns (h). a) A horned bull is mated to a hornless cow, which is heterozygous. What kind of offspring are to be expected and in what ratio? b) If the cow is next mated to a hornless bull, which is also heterozygous, what is the chance that the first calf will have horns? c) Assuming that the first calf has horns, what is the chance that the second calf will be hornless?

          2) In cattle, the hornless condition (H) is dominant to that for
the possession of horns (h).
a) A horned bull is mated to a hornless cow, which is
heterozygous. What kind of offspring are to be expected and in what
ratio?
b) If the cow is next mated to a hornless bull, which is also
heterozygous, what is the chance that the first calf will have
horns?
c) Assuming that the first calf has horns, what is the chance
that the second calf will be hornless?

Step 1

- The horned bull has the genotype \( hh \) because the horned condition is recessive. - The hornless cow is heterozygous, so her genotype is \( Hh \). Show more…
