A dominant allele is an allele that shows the effect even if the individual has only one copy of this allele. If alleles are codominant, both alleles affect the phenotype while the individual has a mix of both traits encoded by both codominant alleles. As a result, if the trait for color is codominant, a chicken that carries the allele for black and the allele for white will show a mix of phenotypes and will be checkered (speckled).

fifty heterozygous brown rabbits are placed with 100 homozygous white rabbits. what are the allele frequencies for brown fur (B) and for white fur (b)?

Answer:p = frequency of the B allele becomes 0.7q = frequency of the b allele = 0.3Explanation:Hardy Weinberg equation is used to calculate frequencies.Hardy Weinberg equation can be written as...

A mole has two alleles for fur color, B = brown fur and b = white fur. In a population of 100 moles, 12 have white fur. What is the brown fur allele frequency?

According to the Hardy-Weinberg principle, 0.65359 or 65.359%.

If fur color in guinea pigs demonstrated incomplete dominance predict what fur color the offspring of a white and a black guinea pig may have if they are mates together and why

If the dominant feature is black AA cross with white aa, then we get a heterohygote Aa.When mixing black and white, it turns gray.

In pea plants, purple flowers are dominant to white flowers. If two white flowers are crossed what percentage of their offspring will aslo be white?

100%Since White is recessive, if you cross aa and aa, the only possible offspring will have aa only

1) In guinea pigs, black fur is dominant over white fur. How could an animal breeder test whether a black guinea pig is homozygous or heterozygous?

If it will be homozygous then all the offspring's of test cross will be of black fur while as if it is heterozygous then black and white fur offspring will...
