In squirrels, bushy tail (B) is dominant to smooth tail (b), and gray coat (G) is dominant to brown coat (g). These two loci are linked. Pure-breeding gray, smooth-tailed squirrels were mated to pure-breeding brown, bushy-tailed squirrels. The F1 were testcrossed. Testcross progeny consisted of 278 gray, smooth-tailed, 21 gray, bushy-tailed, 306 brown, bushy-tailed, and 30 brown, smooth-tailed squirrels. Calculate the map distance between these two genes in centimorgans. Round your answer properly to 2 decimal digits. Type in only the numerical value for your map distance without indicating the units.

Question
In squirrels, bushy tail (B) is dominant to smooth tail (b), and gray coat (G) is
dominant to brown coat (g). These two loci are linked. Pure-breeding gray,
smooth-tailed squirrels were mated to pure-breeding brown, bushy-tailed
squirrels. The F1 were testcrossed. Testcross progeny consisted of 278 gray,
smooth-tailed, 21 gray, bushy-tailed, 306 brown, bushy-tailed, and 30 brown,
smooth-tailed squirrels. Calculate the map distance between these two genes in
centimorgans. Round your answer properly to 2 decimal digits. Type in only the
numerical value for your map distance without indicating the units.
