The frequency of allele if it is evolutionary successful is?
Correct answer: A. Increased
- A. Increased
- B. Decreased
- C. No change
- D. None of these
Explanation
If an allele is evolutionarily successful, its frequency in the population is likely to increase over time. This increase occurs because evolution by natural selection favors advantageous alleles that provide a fitness advantage to individuals carrying them. As a result, individuals with the successful allele have a higher chance of surviving, reproducing, and passing on the allele to their offspring, leading to its spread in the population.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
