Two genes are located on separate chromosomes. One gene determines hair color in foxes, where AA is lethal before birth, Aa is platinum hair, aa is silver hair. A second gene pair B and b determines hair length where short hair is dominant to long hair. A platinum fox that was pure breeding for short hair length is crossed with silver fox with long hair. The F1 contained foxes that were platinum and others that were silver. Two of the platinum F1 foxes were mated. What are the phenotypes and phenotypic ratios for the foxes in the F2 generation. a. 6 platinum short: 2 platinum long: 3 silver short; 1 silver long b. 2 platinum short: 6 platinun long: 1 silver short;3 silver lont c. 1 platinum short: 6 silver long: 2 platinum long: 3 silver short d. 6 silver short: 1 silver long: 2 platinum long: 3 platinum short e. none of these
