Question

the development and spread of a new gene for antibiotic - resistance in a population of bacteria that are exposed to that antibiotic would mean that trait is a(n) __________. consistent phenotype swapped gene disruptive trait stabilizing trait adaptation

Explanation:

An adaptation is a trait that enhances an organism's survival and reproduction in its environment. Antibiotic - resistance helps bacteria survive exposure to antibiotics, increasing their chances of survival and reproduction. A consistent phenotype refers to a trait that is always expressed in a certain way, but this doesn't capture the idea of a beneficial trait for survival. A swapped gene is not the correct term for this context. A disruptive trait would lead to extreme phenotypes being favored over intermediate ones, which is not the case here. A stabilizing trait reduces variation, but antibiotic - resistance is a new and beneficial trait (not just reducing variation).

Answer:

adaptation
