In humans, male-pattern baldness is controlled by an autosomal gene that occurs in two allelic forms. Allele Hn determines nonbaldness, and allele Hb determines pattern baldness. In males, because of the presence of testosterone, allele Hb is dominant over Hn. If a man and woman both with genotype HnHb have a son, what is the chance that he will eventually be bald? Calculate and show your work.

A black Peruvian Rock Rat is crossed with an albino Peruvian Rock Rat. They produce 15 grey offspring. When the same albino rat is crossed with a different black one, 8 grey and 8 albinos are born. What is the best explanation for this genetic situation? In your explanation, write the genotypes for the parents and offspring for both crosses. Hint: This is a combination of TWO different modes of inheritance that we studied.

Domesticated banana plants, which are triploid, are seedless and sterile.a) Propose a possible explanation for their sterility. b) Propose an explanation for how they became triploid in the first place. Hint: Consider the chromosome numbers of the parent plants in your explanation

A certain (hypothetical) organism is diploid, has either blue or orange wings as the consequence of one of its genes, and has either long or short antennae as the result of a second gene. A female with a paternal set of one orange and one long gene chromosomes and a maternal set comprised of one blue and one short gene chromosome is expected to produce what types of eggs after meiosis?
