It is given that bollworms that are susceptible to Bt are represented by either RR or Rr and resistance one are shown by rr genotype and bollworms that are resistant to DDT are represent TT or Tt genotype and susceptible to DDT have tt genotype.

Cross: RR tt with rr TT

Gametes: Rt and rT

F1 cross:

    RT

rT  RrTt ( susceptible Bt and resistant DDT)

F1 Cross with F1

Gametes: RT, Rt, rT and rt

cross:

             RT      Rt        rT         rt

RT       RRTT   RRTt   RrTT    RrTt

Rt        RRTt    RRtt    RrTt      RrTt

rT       RrTT    RrTt     rrTt       rrTt
