Exercise 6

When true-breeding mice with brown fur and short tails ( BBtt )were crossed to true-breeding mice with white fur and long tails ( bbTT ), all F 1 offspring had brown fur and long tails. The F 1 offspring were crossed to mice with white fur and short tails. What are the possible phenotypes of the F 2 offspring Which F 2 offspring are recombinant, and which are nonrecombinant What are the ratios of the F 2 offspring if independent assortment is taking place How are the ratios affected by linkage
