Homework Answers
we have chickens which have two codominant alleles.
this means that both the alleles if present will show their traits in the progeny.
lets consider that we black chickens have the alleles : FBFB
white chicken : FWFW
and the erminette : FBFW
Answer 1) when we cross an erminette with a black chicken we get the following results
FWFB X FBFB
the genes will give result in 50% black chickens and 50% eminettes.
Answer2 ) when we cross a black chicken and a white chicken, we get the following results :
FWFW X FBFB
the resulting progeny of the chicken will be all Eminettes.
i am also attaching an image to give you a better idea of how i took out the answer.
i hope i was able to help you with the answer ! :)

Feather coloration in a variety of chicken is determined by a codominant alleles. if a chicken with white feathers produces offspring with a chicken that has black feathers, what feather coloration would you expect in the offspring? if two chickens with this pattern of feather coloration where to breed, how many of the offspring would have the same phenotype as their parents?

Pigment of chicken feathers is regulated by two genes, the gene for feather pigment C, and a gene that inhibits pigment production, I. A mother chicken, who is homozygous recessive for gene c, and heterozygous for gene I, is crossed with a father chicken, who is heterozygous for the pigment gene, and heterozygous for gene I. • Inhibition is dominant to uninhibited, pigmented feathers are dominant to unpigmented feathers. • The inhibitor gene (I) will prevent expression of pigmented chicken...

3.) In chickens, two genes control feather color—the R gene and the Q gene. The Rallele causes chickens to be red and the r allele causes chickens to be white. R is dominant to r. Likewise, Q codes for red and q codes for white. Q is dominant to q. If a chicken has just one dominant allele of either gene, it will be red. How many red and white chickens would expect in a cross between two chickens that...

In bluebirds, there is an autosomal gene called the feather gene. This gene codes for the feather protein, and this protein controls the color of the feathers. A base- substitution mutation in the feather gene results in a bird with black feathers. When this black-feathered bird mates with a true-breeding normal blue-feathered bird (a black x normal cross), the F1 offspring all have normal blue feathers. Next to each statement below, indicate True or False. The black feather gene allele...

1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...

Question 3 1 pts The color of chickens is determined by gene B, such that BB=black, Bb = gray, and bb = white. A second gene R controls comb shape, with dominant rose and recessive single comb. If a white single-combed chicken is mated with a gray chicken that is heterozygous for rose comb, what fraction of the offspring will be gray with rose comb? 1/4 9/16 1/8 O 3/8 1/16

Fur color in dogs can be black, brown or white. The B gene is responsible for fur color. Dogs that inherit a dominant B will have black fur. Dogs that inherit 2 recessive alleles, bb, will have brown color. There is a second gene that contributes to fur color in dogs: gene I. Individuals who inherit a dominant allele, I, at this location, will always have white color. Individuals who inherit the homozygous recessive condition, ii, will be able to...

A gene for the MN blood group has codominant alleles M and N. If both children in a family are of blood type M, which of the following situations is possible? OA) Each parent is either Mor MN. OB) Both children are heterozygous for this gene. OC) Each parent must be type M. OD) Neither parent can have the N allele.

Question 1 (1 point) In a species of flowering plant, petal color is determined by one gene with two alleles, R and W. Individuals homozygous for allele R have red petals, and those homozygous for allele Whave white petals. Ris dominant to W. You cross a pure- breeding red flowered plant with a pure-breeding white flowered plant to create an F1 generation. You then cross two individuals from the F1 generation to create an F2 generation. What proportion of the...
