  • dominant allele P, expresses purple color
  • PP and Pp are purple flowered-plants
  • pp are red flowered-plants

Cross:

Parental) PP  x  pp

Gametes) P   P   p   p

Punnet square)      P         P

                        p    Pp     Pp

                        p    Pp     Pp

F1) 100% purple flowered-plants

     4/4 = 1 Pp heterozygous individuals
