. In tigers, a recessive allele of a particular gene causes both anabsence of fur pigmentation (a white tiger) and a cross-eyed condition. If two phenotypically normal tigers that are heterozygousat this locus are mated, what percentage of their offspring will becross-eyed? What percentage of cross-eyed tigers will be white?
In humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?
In dogs, the color black is dependent upon the dominant allele B and white upon the recessive allele b. If two heterozygous black dogs mate, what genotypes and phenotypes may show up in the F1 generation?
QUESTION:
What percent of the offspring would you expect to have: A black phenotype and a white phenotype?
