Lets say that tribbles have an X-Y sex determination mechanosm like that of humans. the trait bald (Xb) is X-linked and recessive to furry (Xb+), and the trait long legged (l) is automsomal and recessive to short legged tribbles(L).You make reciprocal crosses between true breeding bald, long legged tribbles and the true breeding furry,short legged tribbles. Do you expect a 9:3:3:1 ratio in the F2 of either or both of these crosses?
Demonstrate the crosses and explain your answer.
