Fur color is an inherited trait controlled by one pair of alleles where one form is dominant over the other. The fur color is either brown or gray. Two brown animals mate and produce 12 offspring. Three (25 percent) of the offspring produced are gray and nine (75 percent) are brown. Based on the above data answer the follow questions Determine which fur color is dominant and which is recessive. Assign letter symbols for the alleles in your answer.

Step 1
Let's assign the dominant allele for brown fur color as \( B \) and the recessive allele for gray fur color as \( b \). Show more…

Brown fur vs white fur. Say that the alleles for fur color (brown or white) are written using the letter “B” and “b”. The dominant trait is brown, white fur color represents the recessive trait. If you crossed two homozygous recessive individuals for fur color, what would be the chances of having an offspring with the white phenotype?

You are a breeder of animals with an X-linked coat-color gene, one allele of which gives black fur and another of which gives white fur. Black fur is dominant to white fur. You have a black-coated female of unknown genotype. What is the genotype of the male you'll cross the female with if you want to figure out whether the female is homozygous or heterozygous for coat color? If you perform this cross, use potential phenotypic ratios in the offspring to explain how you would tell if the mother is homozygous or heterozygous.

Select the correct terms: The (gene / allele] for coat color has two [genes / alleles)-one for brown coloring and one for black.
