butalik [34]

Answer:

Option C, ppAa is indicative of white axial flowers.

Explanation:

It is given that Purple color (P) is dominant over white color (p). Thus in order to have a flower of white color , the flower must be homozygous recessive with an allele pair having two recessive alleles.

Similarly, Axial (A) is dominant over terminal (a) flower. Thus, a flower can be axial in two cases -

a) when both the alleles are same i.e AA

or

b) when one allele is A and the other one is a i.e Aa

Considering the above cases, all possible allele combination that will produce white axial flower are as follows -

ppAA, ppAa

Thus, option C is correct
