- Two pair of alleles are known to interact in the production of feather color in parakeets. Allele B is needed for Blue pigment, whereas the recessive “b” resulted in lack of color. The dominant C is associated with yellow pigment whereas the recessive allele “c” also resulted in lack of color. Blue and Yellow pigments together produce green feather color. Give the genotype of each of the following
- A green bird that has a white off spring
- A yellow bird that has a green parent
- A blue bird that has two parents
- A white bird that had a green parent and a blue parent.

- n an example of recessive epistasis the deposition of pigment into hair follicles of the Labrador Retriever is governed by a dominant gene (C) and lack of deposition by its recessive allele (c). Lack of pigment deposition produces a yellow coat color. The color of pigment is governed by an independently assorting hypostatic gene, the dominant allele (B) produces black pigment and its recessive allele (b) produces brown. What coat color ratio is expected from the cross of a brown dog (bbCc) to a black dog (BbCc)? 1/2 brown, 1/2 black 1/4 black, 1/4 brown, 1/2 yellow 1/2 black, 1/4 brown, 1/4 yellow 3/8 black, 1/8 brown, 1/2 yellow 3/8 black, 3/8 brown, 1/4 yellowLabrador retrievers have 3 varieties of fur colour: yellow, chocolate or black. Two genes are involved, each with a dominant (Y and B) and a recessive allele (y and b). The allele Y codes for the ability to produce hair pigment: Yy and YY dogs have dark pigmented fur but all yy individuals are lighter coloured and yellow. The B allele codes for the ability to make hair with the darkest colouration: BB and Bb individuals have black fur; bb dogs have a lighter shade which is chocolate. In the blank Punnet Square below, calculate and state the ratio of phenotypes that occur with a cross between two individuals with the genotype YyBb.The gene for flower color in snapdragons displays incomplete dominance. Snapdragons homozygous for the allele for red flower color have the genotype FRFR and have red flowers. Snapdragons homozygous for the allele for white flower color have the genotype FWFW and have white flowers. Heterozygous snapdragons, with the genotype FRFW, have pink flowers. A snapdragon that has pink flowers is crossed with a different snapdragon that has pink flowers. What percentage of the offspring is expected to have red, white, and pink flowers?
- The comb shape of chickens is an example of an interesting inheritance pattern.

Select one: a. Phenotype Single Walnut Pea Rose 9/16 3/16 3/16 1/16 b. Phenotype Single Walnut Pea Rose 3/16 1/16 9/16 3/16 c. Phenotype Single Walnut Pea Rose 1/16 9/16 3/16 3/16 d. Phenotype Single Walnut Pea Rose 3/16 9/16 1/16 3/16In chickens, a dominant hereditary abnormality (e.g., creepers) causes death when the genotype is homozygous (CC). The recessive condition (cc) at this locus produces a normal phenotype. Another gene locus with co dominant alleles is known to govern feather color such that the genotype FF = black, ff = splashed white, and Ff = blue. Also, a completely dominant gene W produces white skin. Yellow skin is produced by the homozygous genotype ww. QUESTIONS: In CcFfWw x ccffWw, what proportion of the offspring is: b.2 normal, white feathered, white skinned b.3 yellow skinnedThe presence of second allele (E) affects the coat color of German Shepherd. In particular, the presence of homozygous recessive ee produces yellow German Shepherd. Supposed a male German Shepherd, homozygous dominant for both alleles, is crossed with a female German Shepherd, homozygous recessive for both alleles, what are the phenotypes of the parents?

Genotype Phenotype RRPP walnut combIn Doodlewags (hypothetical creatures), the dominant allele S causes solid coat color; the recessive allele s results in white spots on a colored background. The black coat color allele B is dominant to the brown allele b, but these genes are expressed only in the genotype A-. Individuals that are aa are yellow regardless of B alleles. Six pups are produced in a mating between a solid yellow male and a solid brown female. Their phenotypes are 2 solid black, 1 spotted yellow, 1 spotted black and 2 solid brown. a. What are the genotypes of the male and female parents? Must show work/explain to get full credit. b. What genetic effect is being illustrated in part "a"? Explain in a minimum of 3 sentences.n pea plants, the appearance of flowers along the main stem is a dominant phenotype called axial and is controlled by the T allele. The recessive phenotype, produced by the E t allele, has flowers only at the end of the stem and is called terminal. Seedpod form iS determined by a second gene. The dominant phenotype inflated is controlled by allele C, and a recessive constricted form, produced by allele c. A pure breeding axial, constricted plant is crossed to one that is pure-breeding terminal, inflated. A. The F1 progeny of this cross are allowed to self-fertilize. What is the expected distribution of phenotypic classes among the F2 progeny? -> TTcc t난 CC x Et 1:2:1
- In a mystical bird species, birds with the dominant allele C are white, whereas birds homozygous for the recessive allele care colored. This species also have a second locus that acts as a modifier gene if the bird is colored. If birds are colored and are G- at the second locus, they will be yellow. If they are colored and gg at the second locus, they will be green. You cross a double heterozygous bird and a double homozygous recessive (CcGg x ccgg). What percentage of the offspring will be yellow, and what percentage will be white? O 50, 25 O25, 25 O 33,33 50, 50 25, 50In cats, the locus for orange coat color is sex linked. Male cats that are black have the o+ allele, whereas those that are orange have the o allele. Females can be homozygous for the orange allele or homozygous for the black allele and will express each color, respectively. Heterozygous females are tortoise-shelled or calico, having orange and black patches. A calico cat, in addition to being heterozygous at the orange locus, also is either heterozygous or homozygous for the incompletely dominant, autosomal spotting allele (SS = large spots, Ss = small spots, ss = no spots). Manx tails are caused by a dominant trait that is lethal when homozygous. Long tails are the result of a homozygous recessive genotype. An orange male with small white spots and a manx tail is crossed to a calico female with small white spots and a manx tail. What is the probability of observing a solid black female with no spots and long tail? (Hint: All calico cats are female!)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 heterozygous for gene c, and heterozygous for gene I, is crossed with a father chicken, who is homozygous recessive 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 feathers.
