A) Codominance
B) Incomplete dominance
C) Environmental effects
D) Polygenetic inheritance
E) Monohybrid inheritance

Question

Quizplus · Accepted Answer

Codominance occurs when the heterozygote shows both of the parental phenotypes equally. Incomplete dominance is when the organism can express three different variations for a particular trait. Since the phenotype of the flowers depends on an external condition this is an example of environmental effects on gene expression. Polygenic inheritance is when two or more genes regulate a trait. Monohybrid inheritance is when a trait has a dominant and recessive variation.Bloom's
