Purple is dominant over white. So a purple plant with result with a phenotype of PP or Pp?

What do you do 2 determine if the purple flower is PP or Pp? Do you self pollinate them?

Purple is dominant over white. So a purple plant with result with a phenotype of PP or Pp?
determined by test mating


mating with white plant (recessive)


if PP will result in all purple progney 100%


if Pp will result in both phenotypes purple and white


or self mating will lead to presence of white in progney if Pp
Reply:to determine if its PP orPp, u have to cross pollinate it with a homozygous white plant (pp).





if it has PP phenotype,


PP*pp= Pp, Pp, Pp, Pp ......all the ofsprings will be purple





if it has Pp phenotype,


Pp*pp= Pp, Pp, pp,pp..... 2 offsprings will be purple while 2 will be white.
Reply:they are telling you purple is dominat so it'd be PP. white would be pp. phenotype purple is Pp.
