This is a trait that is a blend of the dominant and recessive gene

Question is incomplete. The complete question is as following:

This is a trait that is a blend of the dominant and recessive gene; inheritance pattern where the phenotype of a heterozygote is intermediate between those of the two homozygotes; neither allele of the pair is dominant but combine and display a new trait.

Incomplete Dominance

Explanation:

When two heterozgous alleles are shown together in the phenotype of an organsim, it is called Incomplete dominance. Each allele blend into a third phenotype which produces distinct phenotypes.

In incomplete dominance neither gene is fully recessive or fully  dominant. for example Blue-feathered chickens which are produced by the fusion of black and a white chicken and none of the alleles is totally dominant.

Hence, the correct answer is Incomplete Dominance.

i believe the answer is a or 1
