The differential reproductive success of individuals who carry a particular allele in a given environment is called ____________.
fixation
selection
evolution
migration
genetic drift
Answer:
selection
Explanation:
Members of a population have genetic variations and differ from each other with respect to one or more genetic traits. Some of these genetic traits become beneficial under the changed environmental conditions. The organisms having these beneficial genetic traits are able to survive better and reproduce more than the organisms lacking these genetic traits. This process is called natural selection. It results in an increased proportion of the alleles for the beneficial genetic traits in the population over generations.
