Question

when one allele is not completely dominant over another and produces a phenotype somewhere between both alleles (for example, red and white flowers producing pink flowers), what is it called?

complete dominance

incomplete dominance

Explanation:

Analyze the question definition

The question asks for the term used when one allele is not completely dominant over another, resulting in a heterozygous phenotype that is an intermediate blend of the two homozygous phenotypes (such as red and white flowers producing pink offspring).

Evaluate the given options

• Complete dominance occurs when the dominant allele completely masks the effect of the recessive allele in a heterozygote (e.g., red and white alleles producing only red flowers).
• Incomplete dominance occurs when the heterozygous phenotype is intermediate between the two homozygous phenotypes, which perfectly matches the description of red and white flowers producing pink flowers.

Answer:

• Complete dominance
• Incomplete dominance (Correct answer)
