A recessive allele (d) of the dancer gene in mice affects the inner ear and results in mice with balance problems and an unusual gait. You learned in class that the A gene, which is on a different chromosome, has an allele, AY,that is dominant for yellow coat color and recessive lethal. You cross a pure-breeding line of dancer mice that have normal coats to a strain with normal gait and yellow coats. In the resulting F1 progeny, 1/2 have yellow coats and normal gaits and 1/2 have normal coats and normal gaits
If you cross the yellow-coated F1 brothers and sisters, in the next generation what proportion of the progeny will have the dancer gait and yellow coats?
