Domain 4 – Evolution: 15-Question Assessment

One of the main ways that evolution can occur is through natural selection. The process usually goes as follows: ​ (a)   exists in a population, mainly from mutations. Overpopulation leads to ​ (b)   , which leads to the more fit individuals surviving and reproducing. This process is always going back and forth because the environment is never ​ (c)   for long. Over time, we see allele frequencies for beneficial mutations ​ (d)   in the gene pool.

​ (a)   can occur through 2 main mechanisms: ​ (b)   where species that are more fit survive and reproduce, and ​ (c)   where random chance events can occur, like a bottleneck or founder effect, and reduce the genetic variation. ​ (d)   is the movement of genes between populations; in other words, migration.

​ (a)   is the process where allele frequencies fluctuate due to random chance, rather than from survival of the fittest. There are 2 main types of this: ​ (b)   effect, where a small population colonizes another area. And the ​ (c)   effect, where a small population is left after a natural disaster. Both of these processes leads to a ​ (d)   in the genetic diversity of the population.
