What percentage of the tearful variety will be produced by crossing two heterozygous pines? 3. In German Shepards, the drooping ear trait is due to a dominant gene, piece of music erect ears is due to a recessive allele. If two heterozygous dogs with drooping ears are mated, w ill any of the pups be plausibly to have d! rooping ears? If so, what percentage can be evaluate? 4. In iguanas, rough tails is a recessive symptomatic which sometimes appears. The normal tail has swimming skin.
