One of the original Amish colonies rose from a ship of colonists that came from Europe. The ship’s captain, who had polydactyly, a rare dominant trait, was one of the original colonists. Today, we see a much higher frequency of polydactyly in the Amish population. This is an example of:

a. natural selection

b. genetic drift

c. founder effect

d. b and c

It is described as a process in which organisms reproduce and survive in diverse ways as a result of phenotypic alterations. It comprises a mild variation of a trait, which is retained if the variance benefits the individuals.

(b) Genetic drift is a term used to describe the process of a person' In a nutshell, genetic drift explains the occurrence of random variations in all forms of gene variants in a population. Genetic drift occurs when different variants of a gene, known as alleles, arise. Changes in allele frequencies are used to measure these alterations in alleles. These allele variants rise and diminish with time. Once genetic drift occurs, alleles are either lost or gained in a population.

(c) The influence of the founder effect. In population genetics, the founder effect occurs when a new population is created by a small number of individuals from a larger population, resulting in a shift and reduction in genetic variety.

(d) is represented by the letters b and c. Both of these options limit a population's genetic diversity. Polydactyly is more common in Amish colonies due to genetic drift and the founder effect. As a result, option is the proper response (d).

(a) Natural selection is a natural process in which an organism reproduces in a favorable environment and passes on its characteristics to the following generation. With time, organisms adapt to their surroundings and allow this process to take place. As a result, this is a fundamental evolutionary strategy that aids in the change of heritable features, and these qualities of a population are handed down across generations.
