tatiyna

Answer:

The correct answer will be- Non-Mendelian inheritance (incomplete dominance)

Explanation:

Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.

In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.

Cross

RR (red) x rr (white) = Rr (pink)

Thus, incomplete dominance is the correct answer.
