  1. Ch. 8 “Genetic Crosses That Involve Two Traits”

  2. #1. What are the phenotypes (descriptions) of rabbits that have the following genotypes: Ggbb = gray fur/red eyes ggbb= white fur/red eyes ggBB = white fur/black eyes GgBb = gray fur/black eyes

  3. #2. Phenotypic Ratios of Two Trait Crosses • gray fur & black eyes = 8 • gray fur & red eyes = 8 • white fur & black eyes = 0 • white fur & red eyes = 0

  4. #3. Phenotypic Ratios of Two Trait Crosses • gray fur & black eyes = 9 • gray fur & red eyes = 3 • white fur & black eyes = 3 • white fur & red eyes = 1

  5. #4. Phenotypic Ratios of Two Trait Crosses • gray fur & black eyes = 12 • gray fur & red eyes = 4 • white fur & black eyes = 0 • white fur & red eyes = 0
