The white Leghorn breed of chickens is homozygous for the dominant allele C, which produces colored feathers. However, this breed is also homozygous for the dominant allele I of an independently assorting gene that inhibits coloration of the feathers. Consequently, Leghorn chickens have white feathers. The white Wyandotte breed of chickens has neither the allele for color nor the inhibitor of color; it is therefore genotypically cc ii. What are the F2 phenotypes and proportions expected from intercrossing the progeny of a white Leghorn hen and a white Wyandotte rooster?
In Drosophila, an allele causing vestigial wings is 12.5 mu away from another gene that causes purple eyes. A third gene that affects body colour has an allele that causes black body colour. This third gene is 18.5 m.u. away from the vestigial wings gene and 6 m.u. away from the gene causing purple eyes. The alleles causing vestigial wings, purple eyes and black body are all recessive. The dominant (wildtype traits) are long wings, red eyes, and grey body. A researcher crossed wild-type flies to flies with vestigial wings, purple eyes and black body. All F1 flies were wildtype. F1 females were crossed to males with vestigial wings, purple eyes and black body. If 1,000 offspring were observed, what are the expected numbers of the following types of flies: Long wings, red eyes, grey body Long wings, purple eyes, grey body Long wings, red eyes, black body Long wings, purple eyes, black body Short wings, red eyes, grey body Short wings, red eyes, black body Short wings, purple eyes, grey…
In a certain plant, leaf size is determined by fourgenes whose alleles assort independently and actadditively. Thus, alleles A, B, C, and D each add4 cm to leaf length and alleles A′, B′, C′, andD′ each add 2 cm to leaf length. Therefore,an AA BB CC DD plant has leaves 32 cm longand an A′A′ B′B′ C′C′ D′D′ plant has leaves16 cm long.a. If true-breeding plants with leaves 32 cm longare crossed to true-breeding plants with leaves16 cm long, the F1 will have leaves 24 cm longand the genotype AA′ BB′ CC′ DD′. Listall possible leaf lengths and their expectedfrequencies in the F2 generation produced fromthese F1 plants.
In pigs, the dominant C allele produces a curly tail. c/c homozygotes have straight tails. The recessive w allele produces white hair, whereas the W allele produces brown hair. The C and W genes (loci) are on the same chromosome. A C W / c w heterozygote (curly, brown) is test crossed to a c w / c w (straight, white) homozygote multiple times. They produce a total of 100 progeny, of which 20 have curly tails and white hair. What is the distance between the C and W loci, in map units? A.10 B. 20 C. 30 D.40

In chickens, comb shape is determined by genes at two loci (Gene 1 has alleles R, r and Gene 2 has alleles P, p). A walnut comb is produced when at least one dominant gene R is present at one locus and at least one dominant gene P is present at a second locus (genotype R_P). The genotype R_pp gives a rose comb phenotype; rrP_gives a pea comb phenotype; and rrpp gives a single comb phenotype. Based on this information give specific genotypes for comb shape of the parents in the crosses listed below: A) Walnut crossed with single produces 1 walnut, 1 rose, 1 pea and 1 single offspring. B) Rose crossed with pea produces 20 walnut offspring. C) Pea crossed with single produces 1 single offspring.
Certainly, not all Muppets look like the one shown in the picture below, nor do they all look the same. In fact, there’s a great deal of phenotypic variation in Muppets. Two traits that have been particularly well-studied are curly hair presences and skin color. One individual is a male, and he possesses a green skin and no hair, whereas the female individual possess a curly hair and pink skin. Let’s call the gene controlling skin coloration S and that controlling hair H. In this species, both hair and green skin are recessive traits. Both of the individuals shown are homozygous. 1.

As seen in the photo, Labradors come in three colors-- black, brown and yellow. What is the genetic basis for these different coat colors? One gene produces melanin, a pigment which is deposited in the dog's fur and makes the color dark. With this gene, allele B (black) is dominant to allele b. Only in the case of a recessive homozygote (bb) will the dog's phenotype be brown. The regulatory gene is separate from the melanin gene but it acts as a switch, either turning the melanin gene on or turning it off. Allele E is dominant and allows for the melanin to be deposited in the dog's fur ("on" switch), but if the switch gene is a recessive homozygote, the melanin is blocked ("off" switch) and a yellow dog is the result! 1. Two other Labradors mate and produce puppies. Their genotypes are Bbee and BbEe. What color are each parent and what are the phenotypic rations of their offspring in the F1 Generation?
