Answer:
Heterozygous and dominant
Explanation:
When Mendel performed the purebred purple flower with the purebred white flower he found that the purple flowers were obtained.
Suppose,
the genotype of the purple flower is- PP (purebred)
the genotype of white flower- pp ( purebred)
crossing them we obtain
PP x pp
P P
p Pp Pp
p Pp Pp
We see that all the offspring obtained are heterozygous (Pp) and are purple colored.
This shows that the allele for the purple flower is dominant.
Thus, heterozygous and dominant is correct.
