Concept explainers
The evolution is the alteration in the heritable features of the biological population over a successive generation. The evolution on a small scale (microevolution) is referring to the alteration in allele frequencies within a one population. The allele frequencies may alter due to the four fundamental forces of evolution that includes mutations, natural selection, genetic drift and gene flow.
Answer to Problem 1TQ
The founder effect is a type of genetic drift in which individuals in one small group of a large population establish a new distant population and then reproduce.
Explanation of Solution
The founder effect is a special type of genetic drift. It occurs when a small group present in the population splinters off from the original population and establish a new one. Thus, the founder effect takes place if some individuals of large population form a new distant population at diverse place and reproduce. The genetic drift is the variation in the frequency of an existing gene variant found in a population due to random sampling of an organism.
