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). If a BbRr individual is mated with a bbrrindividual the expected phenotypic ratio of the offspring is 1 black-red : 1 black-white: 1 green-red : 1 green-white. However, when you mate these individuals you find that the phenotypic ratio of the offspring is 6 black-red :1 black-white : 1 green-red : 6 green-white. What could account for this difference?

#Section 3: Genetics, Cellular and Molecular Biology

  1. The genes for hair color and the genes for eyecolor are carried on different chromosomes

  2. The expected results did not take genetic recombination into account

  3. The genes for hair color and eye color are linked

  4. The genes for hair color and eye color show dependent assort
