Answer :
The two populations' different retinitis pigmentosa allele frequencies were most likely the result of genetic drift brought on by a founder event.
What does the founder effect mean?
A genetic modification known as the "founder effect" occurs when one or more ancestors had the altered gene. This genetic mutation is frequently seen in geographically or culturally isolated groups.
When a small portion of the original population establishes a new colony, a founder effect happens. Due to its tiny size, the colony can have less genetic variety from the original population. a non-random selection of the genes from the starting population.
Only a small portion of the genetic variety of the parental population is carried by these founding individuals; as a result, the founder effect causes a reduction in genetic diversity and distinctive allele frequency patterns in the newly founded population.
