In guinea pigs, white coat (w) is recessive to black coat (W) and wavy hair (v) is recessive to straight hair (V). A breeder crosses a guinea pig that is homozygous for white coat and wavy hair with a guinea pig that is black with straight hair. The F1 are then crossed with guinea pigs having white coats and wavy hair in a series of testcrosses. The following progeny are produced from these testcrosses: black, straight 30 black, wavy 10...

Yellow coat color in guinea pigs is produced by the homozygous genotype, YY, and white is produced by the homozygous genotype, yy. One homozygous yellow guinea pig crosses with a homozygous white guinea pig to produce cream guinea pigs. a. What pattern of inheritance does this follow (complete, incomplete or co-dominance)? How do you know? b. Draw a Punnett square for a cross between two cream guinea pigs. What are the genotypic and phenotypic ratios?

11. In a particular species of mammal, black hair (B) is dominant to green hair (b), and red eyes (R) are dominant to white eyes (r). When a BbRr individual was mated with a bbrr individual, the observed distribution of offspring was as follows: black-red 1,070; black-white 177; green-red 180; green- white 1,072. A. Based on these results, are the genes for hair color and eye color linked or unlinked? B. Do our results follow Mendel’s law of independent assortment?...
