n the Asiatic Black Bear (a normal XX:XY mammal XX: species) there are two traits under investigation. One trait is a white chest spot which can be either circular (+) or oval (ov). The second trait relates to the fur color with two phenotypes: black (+) and a reddish brown (b). A reddish brown female with a circular chest spot was crossed to a black male also with a circular chest spot. Use this information and the data below on their offspring to answer the following questions: Males: All reddish brown colored with 75% circular spot and 25% oval spot. Females: All black colored with 75% circular spot and 25% oval spot a) Which general type of chromosome does each trait reside on? Fur color gene ________________ Chest spot gene _________________ b) What are the genotypes of the two individuals that were crossed? c) What would the phenotypes and phenotypic ratio be if the original female was crossed with a reddish brown male with an oval chest spot?
