Info: I ALMOST HAVE 200 QUESTIONS ANSWERED! (_¿? Question: ¿?_)

Which of the following statements is true?

Options:

A. Gene flow evens out genetic differences between populations.

B. Genetic drift increases the genetic differences between populations.

C. Natural selection, mutation, and genetic drift are random events.

D. The bottleneck effect increases the genetic diversity of a population.

Natural selection, mutation, and genetic drift are random events.

Explanation:

A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.  

Hope this helps :)

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
