What percentage of the pendulous variety will be produced by crossing two heterozygous pines? 3. In German Shepards, the drooping ear trait is due to a dominant gene, objet dart erect ears is due to a recessive allele. If two heterozygous dogs with drooping ears are mate d, will any of the pups be plausibly to ha! ve drooping ears? If so, what percentage can be expect? 4. In iguanas, wartlike tails is a recessive device characteristic which sometimes appears. The normal tail has self-possessed skin.
