1.In aliens, a glossy exoskeleton (G) is dominant to a dull exoskeleton (g). Also, excessive drooling (D) is dominant to no drooling (d). An alien drone (male) with a glossy exoskeleton and excessive drooling is crossed with an alien queen that is homozygous recessive for both traits. The following offspring were produced: 432 glossy and excessively drooling, 453 dull and excessively drooling.
a. What is the genotype of the alien drone (male)?
Answer: GgDD or is it GgDd?
2. 4. In guinea pigs, white coat (w) is recessive to black coat (W) and wavy hair (v) is recessive to straight hair (V). A guinea pig that is black with straight hair but has an unknown genotype is crossed with guinea pigs having white coats and wavy hair in a series of test crosses. The following progeny are produced from these testcrosses: 30 Black, straight; 10 Black, wavy; 12 White, straight; and 31 White, wavy.
a. What is the genotype of the unknown parental guinea pig?
Answer: Is it WvVv? Not sure how to figure it out
b.If these genes are segregating independently, what is the expected phenotypic ratio for the cross? Support your assertion with a Punnett square.
Answer: is it 1:1 for white to black and 1:1 for wavy to straight? And if so why?
Make a hypothesis that explains your results.
