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

Answer:speciation
Explanation: Speciation is the evolutionary process by which populations evolve to become distinct species. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another these are allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.
