In mice, a trait called snubnose is recessive to a wild-type nose, atrait called pintail is dominant to a normal tail, and a trait calledjerker (a defect in motor skills) is recessive to a normal gait.

Question
In mice, a trait called snubnose is recessive to a wild-type nose, a
trait called pintail is dominant to a normal tail, and a trait called
jerker (a defect in motor skills) is recessive to a normal gait. Jerker
mice with a snubnose and a pintail were crossed to normal mice,
and then the F1 mice were crossed to jerker mice that have a snubnose
and a normal tail. The outcome of this cross was as follows:
560 jerker, snubnose, pintail
548 normal gait, normal nose, normal tail
102 jerker, snubnose, normal tail
104 normal gait, normal nose, pintail
77 jerker, normal nose, normal tail
71 normal gait, snubnose, pintail
11 jerker, normal nose, pintail
9 normal gait, snubnose, normal tail
Construct a genetic map that shows the order of these genes and
distances between them.
