Question

A large plant population may impose selective pressure on a smaller, isolated group of plants, resulting in a change in allele distribution. which mechanism is responsible for this change in the allele distribution? mutation hybridization trait acquisition genetic drift

Answer 1

The answer is genetic drift. This is the change of allelic frequency in a population due to natural selection in favor of particular traits. The effect of natural drift is greater is a population of small size that in a big population. When the allelic frequency of the isolated group of plants reaches 0, it is deemed as lost.
