a) pr is the middle locus.

a) v-pr recombination fraction = 82 + 79 + 44 + 42 =  nr 
a) v-pr recombination fraction = 82 + 791109             n

                                         =  247 
                                            1109

                                         = 0.2227
                                         = 22.3%

a) pr-bm recombination fraction = 200 +195 + 44 + 42
a) pr-bm recombination fraction = 200 +1109

a) pr-bm recombination fraction = 0.4337
a) pr-bm recombination fraction = 43.4%

b)

c)  44 + 42  =  nr  = 0.0775 = 7.8% observed
c)    1109        n

86 observed d.c.o. gametes

c) 0.2227 x 0.4337 = 0.09658 = 9.7% expected
c) 0.09658 x 1109 = 107 expected d.c.o. gametes

c) c =   86  = 0.804          I = 1 - c = 1 - 0.804 = 0.196
c)       107
