Verified
A gene that only influences the expression of a trait when paired with another less active gene is called _______.
A) recessive
B) mutated
C) recombinant
D) dominant
Recessive
Pertaining to a gene that is expressed in the phenotype only when its allele is identical, needing two copies (one from each parent) to exhibit the trait.
Dominant
Referring to a trait, gene, or characteristic that supersedes another in genetic expression when both are present.
- Master the introductory concepts of genetics, which involve terminology such as genes, chromosomes, DNA, and the mechanisms of dominant and recessive genes.
- Explore the detailed mechanisms underlying the inheritance of traits, paying special attention to how dominant and recessive genes impact physical features.

Final Answer :
A
Explanation :
A gene that only influences the expression of a trait when paired with another less active gene is called a recessive gene. This means that it is only expressed when paired with another copy of the same recessive gene. When paired with a dominant gene, the dominant gene will be expressed, masking the recessive gene's effect. Mutated, recombinant, and dominant do not accurately describe this type of gene.
