Answer:

Genetic drift

Explanation:

  • Genetic drift is the mechanism that results in a change in the distribution of alleles within an isolated group of organisms.
  • In this case, a group of yellow violet plants became isolated from a large violet plant population causing a change in allele distribution.
  • This is a result of genetic drift which is a random process that may cause allele frequency change over a short period.
  • The process may, therefore, result in the loss of genetic variation due to the alteration of allele frequency in a population.
