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).

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
