Question

some flowering plants appear to have offspring that have traits that are intermediate between those of the parents. which type of dominance is exhibited by the offspring?
○ complete dominance
○ blended dominance
○ codominance
○ incomplete dominance

Explanation:

To solve this, we analyze each option:

• Complete dominance: One allele completely masks the other, so offspring show the dominant trait, not intermediate. Eliminate this.
• Blended dominance: Not a recognized term in genetics for dominance types. Eliminate this.
• Codominance: Both alleles are expressed fully (e.g., AB blood type), not an intermediate trait. Eliminate this.
• Incomplete dominance: The heterozygous offspring show a phenotype that is intermediate between the two homozygous parents (e.g., red and white flowers producing pink offspring). This matches the description of offspring with intermediate traits.

Answer:

D. incomplete dominance
