In fruit flies, the allele for long wings (A) is dominant to the allele for short wings (a), and the allele for light brown body color (B) is dominant to the allele for ebony body color (b). What is the genotype of a fruit fly that is homozygous dominant for wing length and heterozygous for body color? aaBB AаBb О ААВЬ AAbb aabb
The dominant allele H reduces the number of bodybristles in fruit flies, giving rise to a hairless phenotype. In the homozygous condition, H is lethal. Thedominant allele S has no effect on bristle number except in the presence of H, in which case a single S allele suppresses the hairless phenotype, thus restoringthe bristles. However, S is also lethal in homozygotes.a. What ratio of flies with normal bristles to hairlessindividuals would we find in the live progeny of across between two normal flies both carrying theH allele in the suppressed condition?b. When the hairless progeny of the previous cross arecrossed with one of the parental normal flies frompart (a) (meaning a fly that carries H in the suppressed condition), what phenotypic ratio wouldyou expect to find among their live progeny?
In humans, "unattached" earlobes are dominant over "attached" earlobes. "Widows peak" hairline is dominant over "non-widows peak" hairline. Use E and e for the earlobe phenotype alleles, and W and w for the hairline phenotype alleles. A female and a male, both with genotype EeWw have a child. What is the probability it will be a boy, and have attached earlobes and a widows peak hairline?
In domestic chicken, feather colour and shape are two traits which are controlled by autosomal alleles that are co-dominant. Table 2 shows the alleles and phenotype of both traits. The heterozygous state for feather colour is grey while the heterozygous state for feather shape is mildly frizzled. TABLE 2 Trait Feather colour Allele CB CW SS SF Effect Produces black feathers in homozygotes Produces white feathers in homozygotes Produces straight feathers in homozygotes Produces frizzled feathers in homozygotes Feather shape A farmer bred a black frizzled rooster with a grey mildly frizzled hen. Draw a genetic diagram to show the expected results of this cross. Include in your answer the phenotypic ratios. Is it necessary to do a test cross to determine the genotypes of the offspring? Explain your answer. The farmer would like all his chickens grey and mildly frizzled. What would you advise him to do? Explain your answer.
In chickens, comb shape is determined by alleles at two loci (R, r and P,p). A walnut comb is produced when at least one dominant allele R ispresent at one locus and at least one dominant allele P is present at asecond locus (genotype R_ P_). A rose comb is produced when at leastone dominant allele is present at the first locus and two recessive allelesare present at the second locus (genotype R_ pp). A pea comb isproduced when two recessive alleles are present at the first locus and atleast one dominant allele is present at the second (genotype rr P_). Iftwo recessive alleles are present at the first and at the second locus (rrpp), a single comb is produced. Progeny with what types of combs andin what proportions will result from the following crosses? a. RR PP × rr pp b. Rr Pp × rr pp c. Rr Pp × Rr Pp d. Rr pp × Rr pp e. Rr pp × rr Pp f. Rr pp × rr pp
In rabbits, the color of body fat is controlled by a single genewith two alleles, designated Y and y. The outcome of this traitis affected by the diet of the rabbit. When raised on a standardvegetarian diet, the dominant Y allele confers white body fat,and the y allele confers yellow body fat. However, when raisedon a xanthophyll-free diet, a homozygote yy rabbit has whitebody fat. If a heterozygous rabbit is crossed to a rabbit withyellow body fat, what are the proportions of offspring withwhite and yellow body fat when raised on a standard vegetariandiet? How do the proportions change if the offspring are raisedon a xanthophyll-free diet?
In certain species of flies, eye color is controlled by sim-·ple dominance by a single pair of alleles. A red-eyed fly was crossed with a white-eyed fly, both of whose parents had white eyes.

In rabbits, fur colour can be either grey, black or blotchy. Blotchy is present as grey and black spotspresent in no specific pattern. Males are almost always either grey or black, while females can begrey, black or blotchy. However, a male individual is found that shows the blotchy pattern, and youexpect a non-disjunction event might be to blame. Explain the inheritance of coat colour in rabbits,and also provide an explanation for the blotchy male.
In cats, the allele (B) produces black color but (b) producesyellow color. These alleles are co‐dominant to each other. Aheterozygote produces a tortoise‐shell color. The alleles (B)and (b) are sex‐linked as well. Cross a tortoise‐shell femalewith a yellow male. What percent of their offspring will be yellow? What percent of their offspring will be black? What percent of their offspring will be tortoise shell?
In rabbits, black hair is dependent on a dominant allele B, and brown upon arecessive allele b. Short-hair is due to dominant allele S and long hair to arecessive allele s.
