You want to measure the distance between two linked genes in guinea pigs (hair color and nose color). You cross two true. breeding strains with opposite phenotypes together, and then you test-cross the F1 offspring. The counts for the offspring are as followed: 335 brown hair, pink nose 105 brown hair, black nose 92 yellow hair, pink nose 318 yellow hair, black nose What is the distance between the two loci in CM?

1) Coat color in mice is determined by several independently assorting autosomal genes. Gene A is involved in the distribution of pigment along the hair. A dominant allele (A) produces a hair color called "agouti"--the hair has dark pigment at the base and tip of each hair shaft and yellow pigment in the central portion of the shaft. Homozygous recessive mice (aa) are missing the yellow stripe and thus have solid dark-colored hair. Gene B is involved in the color...

What would be the phenotypic ratio of the Fa complete dominance is the pattern of inheritance, what would be and phenotypic ratios for the offspring of a true breeding purple, starchy generation? 2.

6. In tigers, a dominant allele (W) is responsible for the expression of the normal orange pigment. Individuals that inherit twe recessive alleles (w) lack the normal orange pigment in their fur, appearing white with black stripes. A pair of normally colored parewis produces a cub that is white with black stripes and scab that is orange with black stripes. What are the possible genotypes of the cube? b. What are the possible genotypes of the parents? 6. Explain your...
