Question

Which inheritance pattern results when parents are crossed for pure traits and the resulting offspring have traits that appear to blend?
incomplete dominance
codominance
Mendelian inheritance
polygenic inheritance

Answer 1

incomplete dominance is correct

Answer 2

The right answer is incomplete dominance

Incomplete dominance is when hybrids of the F1 generation have an intermediate phenotype (between the two phenotypes) compared to the parental P1 generation. This phenomenon occurs in heterozygous individuals.

Example: The color of snapdragon flowers.

The pink color obtained in the F1 generation is incomplete dominance. These flowers are heterozygous. When we cross the flowers obtained in the F1 generation to obtain the F2 generation, we obtain a ratio of genotypes and phenotypes that is the same or 1: 2: 1.
