Question
Which of the following scenarios describes an example of founder effect?
Some of the rare, red-winged finches from a small island fly to a nearby island to feed. They mate with the native brown-winged finches, which results in an increase in the red-wing allele frequency on the new island.
In a population of rabbits, some individuals have spotted fur, which makes them more susceptible to predation. The proportion of rabbits that have spots decreases in the population for several generations.
A small number of British colonists occupied a small island between South America and Africa during the early 1800's, establishing a new population. This population has different allele frequencies from the original population of Britain.
A mistake during DNA replication causes the offspring of a yellow flowering plant to have blue flowers. The blue flower trait is passed on to successive generations.
Explanation / Answer
Answer: A small number of British colonists occupied a small island between South America and Africa during the early 1800's, establishing a new population. This population has different allele frequencies from the original population of Britain
Reason:
Answer: A small number of British colonists occupied a small island between South America and Africa during the early 1800's, establishing a new population. This population has different allele frequencies from the original population of Britain
Reason:
Founder effect: A considerable change in the allelic frequency due to change in selection coefficient of the predominantly produced from the sampling effects if there are a very low population number obtained from a considerably big population primarily and forming colonies in a new area result in a new population. Therefore, a small population from Britain migrated to a small island between South America and Africa during the early 1800's, establishing a new population result in inbreeding of the population already existing there to generate genetic variation genotypically & phenotypically different from the allele frequencies from the original population of Britain.
