Exam 15: A: Nonadaptive Evolution and Speciation Urban Evolution

Founder effect describes a A) new population arising from a migration of a population. B) new population arising from a few individuals. C) population that has undergone mutation. D) population that is largely interbreeding. E) population that results from one species crossing with another.

There are 13 species of finch inhabiting the Galápagos islands,all of which descend from just one species from the mainland.Given this,what do you suppose were the characteristics of the founding population in terms of number of individuals and allelic diversity of those founding individuals?

All of the following are true of genetic bottlenecks,EXCEPT

Which of the following is a stressor for city mice?

Why are there no monotremes (egg-laying mammals)in the Americas?

Reproductive isolation based on location or geography is referred to as

Would the bottleneck effect that removes 25% of individuals have a greater impact on a population of 25 birds or a population of 25,000 birds? Explain.

The Galápagos finches evolved from an ancestor from

From the Hardy-Weinberg equilibrium you can conclude that all populations are evolving. Explain.

Pollen from a tomato plant lands on a grapefruit flower.The pollen fails to grow a pollen tube.This is an example of
