In mice, the recessive traits bent (b=bent tails) and rough (r=ragged fur) are linked on an autosome. Pure breeding bent mice were crossed to pure-breeding rough mice, and the resulting F1 sons and daughters were interbred, with the following results: (Not a test cross)
Wild-type: 204
Bent tails: 92
Rough Fur: 100
Bent & rough: 4
Total: 400
What is your best estimate in map units of the distance between bent and rough?
