If early viking explorers in greenland and north america had survived and become the main ancestors of early north american settlers, rather than the mixture of immigrants from across europe and other continents, today there would be a much higher incidence of nordic traits in the u. s. population. such a scenario would demonstrateselect one: a. gene flow from continent to continent. b. the bottleneck effect. c. genetic drift among the original viking explorers. d. directional selection. e. the founder effect.

e. The founder effect is the correct answer.

Explanation:

It is the reduction of genetic variation which results due to small subset of large population is used to establishing colony and the new population becomes different from the original population. In some cases new species also emerge. This phenomenon occurs when a group of people migrate to other population. the subset carries the genetic information of a larger population which leads to the redaction of genetic variation in the population, and to the emergence of Phenotype. It can lead to increase in one type of gene and reduction of others.
