1) d = right handed
r = left handed
RR x Rr = RR, RR, Rr & Rr
Ans. 1/2 RR (Pure bred right handedness) and 1/2 Rr (hybrid right handedness)
2) d = terminal
r = axial
TT x Tt = TT, TT, Tt & Tt
Ans. 1/2 TT (pure bred terminal) 1/2 Tt (hybrid terminal)
3) d = tall
r = short
tt x Tt = Tt, Tt. tt & tt
Ans. 1/2 Tt (hybrid short) 1/2 tt (pure bred short)
The appropriate solution for this is actually with the Use of Punnet square but since i can't make a punnet square here i just stated the answer.
Hope this helps :)
