Question

In, pea plants purple flowers (P) are dominant over white flowers(p) and axial position (A) is dominant over terminal flower position (a). If you cross two heterozygotes (AaPp) for both traits, what would be the genotypic and phnotypic ration of their offsprings.(Dont forget to show punnet square)

Answer 1

Parent- AaPp X AaPp
Gametes--- AP Ap aP ap AP Ap aP ap

Offsprings
AP Ap aP ap
AP AAPP AAPp AaPP AaPp
Ap AAPp AAppAaPp Aapp
aP AaPP AaPp aaPP aaPp
ap AaPp Aapp aaPp aapp

Phenotypic Ratio: - Axial Purple : Axial White : Terminal Purple : Terminal White
9 : 3 : 3 : 1

Genotypic Ratio:- AAPP : AAPp : AaPP: AApp : AaPp: aaPP : Aapp : aaPp: aapp
1 : 2 : 2 : 1 : 4 : 1 : 2 : 2 : 1

Answer 2

Thank You so much i have been stuck on this and two others forever!
