Question

In a small, isolated population of piranhas, one individual is born with a synonymous mutation in a gene that codes for hemoglobin. after five generations, 5% of the piranhas carry this mutation. what is a plausible explanation for this evolution?

Answer 1

The most likely explanation for the evolution is the genetic drift. The genetic drift is an instrument of development in which allele occurrences of a population alter in excess of generations due to chance or called as sampling error. Genetic drift happens in all populations of non-infinite size but its effects are sturdiest in small inhabitants.
