Dominance the dominant allele doesn’t fully mask or hide the recessive. for example, a red carnation with a white carnation will produce a carnation. one gene one trait. well most of the time than one gene controls a trait. we are all different but genetically speaking we are % similar with regards to genetic makeup.

The correct answer for the blanks are-

1) In incomplete dominance

2) Pink carnation.

3) More than one.

4) 99.9 %

Incomplete dominance (also known as partial dominance) occurs when a dominant form of a gene does not completely masks the expression of another gene variant ( that is a recessive allele).

A heterozygote results in a blend of phenotype ( that lies between the phenotypes of two homozygous parents).

In this question, a red carnation with a white carnation will produce a pink carnation due to incomplete dominance.

When traits are controlled by more thgan one gene, they are called polygenic traits ( this conditon occurs most of the times). We humans exhibit different phenotypes due to differential expression of genes but genetically we all share 99.9 % similarity ( which relates to the genetical material).
