1. Consider two genes in the rabbit. Allele C is dominant and produces rabbits with full color. The recessive allele c produces albino rabbits. The second gene controls the color of the fat. Allele Y produces rabbits with white fat and the recessive allele y produces yellow fat. A series of 2-point test crosses with a dihybrid rabbit produced the following progeny: albino with white fat, 22; full color with white fat, 3; albino with yellow fat, 4; full color with yellow fat, 21.

What is the map distance between genes C and Y? Enter only the number and not the unit.

2. Consider another pair of genes in the same rabbit. Allele B is dominant and produces black-coated rabbits. The recessive allele b produces brown-coated rabbits. The second gene is the same gene given above in questions 17a which controls color of the fat. Allele Y produces rabbits with white fat and the recessive allele y produces yellow fat. A series of 2-point test crosses with a dihybrid rabbit produced the following progeny: black with white fat, 28; brown with white fat, 11; brown with yellow fat, 32; black with yellow fat, 9.

What is the map distance between genes B and Y? Enter only the number and not the unit.

In rabbits, the color of body fat is a diet conditional trait. The mutant allele y results,in the homozygous condition, in yellow body fat with a normal xanthophyll-rich diet but white fat on a xanthophyll-free diet. The dominant wildtype allele Y results in white body fat regardless of diet. What would be the expected phenotypic ratios from the monohybrid cross with and without xanthophyll in the diet? A.) with xanthophyll all white; without xanthophyll 3:1 white: yellow B.) with xanthophyll...

3.Although there are likely more, there are five major genes that interact to control coat colour in mice. These are: A, B, C, D and S. The A allele produces a phenotype called agouti, which caused by a band of yellow colour on a dark hair shaft. The result is a brindled or salt and pepper appearance. The non-agouti (controlled by the a allele) lacks the yellow band and is a solid black. The B gene controls the colour of...

8. Imagine that coat color in dogs is determined by two genes, each of which has two alleles: The dominant P allele of the pigment gene allows the dog to produce black pigment, while the recessive p allele is a null allele that does not produce any pigment. The dominant T allele of the transporter gene makes a transporter protein that transports the pigment into the hair cells, while the recessive t allele is a null allele that does not...

1. Labrador retrievers come in several colors: brown, black, or yellow. In a cross of a black female with a brown male, results can be either all black puppies, 1/2 black to 1/2 brown puppies, or 3/4 black to 1/4 yellow puppies. What to these results indicate?        A. Yellow is dominant to black.         B. Black is dominant to brown and to yellow.         C. Brown is dominant to black.         D. There is incomplete...

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...

A phenotypically wilptype F1 female fruit fly that was heterozygous for genes controlling body color and wing length was crossed to a homozygous mutant male tester with black body (mutant allele b) and vestigial wings (mutant allele vg). a. Symbolize the genotype of the dihybrid female and tester male using appropriate Drosophila gene symbolism using b+ and vg+ for the wildtype dominant alleles; b and vg for the recessive mutant alleles. b. What is the genotype of the F1 dihybrid...

In golden retrievers, the D/d gene codes for an enzyme that produces a pigment. The dominant allele (D) results in a golden pigment, while the recessive allele (d) codes for red pigment. Additionally, the V/v gene produces a transport protein responsible for depositing the pigment produced by D/d into the hair. When the dominant V allele is present, the color expressed by D/d will be deposited and the dog will be that color (golden or red). However, allele v is...

Please answer all the questions, they're related The autosomal recessive allele bw, for brown eyes in Drosophila interacts with the X-linked recessive allele, v, for vermilion eyes, since flies that are recessive for both genes have white eyes. Wild type flies have red eyes. What eye color phenotypes, in what proportions, would be expected in the progeny from a cross of a white-eyed female and a brown eyed male?  Choose the best answer. Select one: a. all females with brown eyes,...
