Question

The phenotype of the heterozygote is intermediate between those of the two homozygotes, on some quantitative scale (color, size, etc.).

a. true
b. false

Answer 1

Incomplete dominance is a genetic phenomenon where the phenotype of a heterozygote is intermediate between those of the two homozygotes, demonstrating a blend of traits. For example, in snapdragons, a cross between a homozygous parent with white flowers and a homozygous parent with red flowers produces offspring with pink flowers.

Step-by-step explanation:

In genetics, the phenomenon described as the phenotype of the heterozygote being intermediate between those of the two homozygotes is called incomplete dominance. This pattern occurs when a heterozygous genotype expresses a phenotype that is a blend or intermediate of the two homozygous genotypes. For example, in snapdragons, a cross between a homozygous parent with white flowers (CWCW) and a homozygous parent with red flowers (CRCR) will produce offspring with pink flowers (CRCW). This demonstrates how the phenotype of the heterozygote is intermediate between those of the two homozygotes.
