SOLVED:Dwarfism is a recessive trait in Hereford cattle. A rancher in western Texas discovers that several of the calves in his herd are dwarfs, and he wants to eliminate this undesirable trait from the herd as rapidly as possible. Suppose that the rancher hires you as a genetic consultant to advise him on how to breed the dwarfism trait out of the herd. What crosses would you advise the rancher to conduct to ensure that the allele causing dwarfism is eliminated from the herd?

Q4: In cattle, there is an allele called "dwarf" which, in the heterozygote, produces calves with legs that are shorter than normal. This allele is homozygous lethal, meaning that homozygous dwarf calves either spontaneously abort early or are stillborn. If a dwarf bull is mated to a dwarf cow, what phenotypic ratio do you expect among the living offspring? Show all work, including identification of alleles and the cross.
