Selectively advantageous

Vedclass · Answer

(D) In evolutionary biology,the frequency of a gene in a population changes due to natural selection. If a mutant gene provides a selective advantage to the organism (i.e.,it is selectively advantageous),it increases the organism's fitness,allowing it to survive and reproduce more effectively. Consequently,the individuals carrying this mutant gene are more likely to pass it on to the next generation,leading to an increase in the frequency of that gene in the population over time. Therefore,the correct answer is $D$.

The frequency of a mutant gene in a population is expected to increase if the gene is ......
