Question

QUESTION 1 Genetic drift is more common in large populations than in small populations. True or False? O True O False QUESTION 2 When one species evolves a new phenotypic feature and another species evolves new adaptations in response, t is called O genetic drift. O coevolution. O gene flow. O sexual selection. O stabilizing selection. QUESTION 3 What events can push a species to extinction? Arial v 3 (12pt) Path: p Words: QUESTION 4 Temporal isolation is an example of O a premating isolating mechanism. O a postmating isolating mechanism. O both a premating and a postmating isolation mechanism O neither a premating nor a postmating isolation mechanism. QUESTION 5 In the context of evolution, equilibrium means O no individuals move into or out of the population. O no change in population size. O no change in allele frequency O equal numbers of males and females. O equal numbers of all alleles.

Explanation / Answer

1. False, its shows more strong effect in small population.

2. coevolution.

3. When a species fails to reproduce and are not able to make adaptation in new or altered environment it become extinct. There are several mechanism through which a species can go for extinction. Such as-

environment- when the environment becomes not suitable for the overall population as a suitable condition for their habitat, then the population can becomes extinct. It can be rapid, like a pollution which is toxoc to the population or can take longer time period.

degradation of habitat- habitat can be degraded due to urbanization, mining, or agricultural practices.

predation or presence of a disease or competition between species also responsible for species extinction.

In some situation loss of one species can lead to loss of another species, if they are dependent on first species for their survival.

4. a premating isolation mechanism.

5.no change in allele frequency.
