What two processes involving chance or randomness lead to an offsprings unique traits ?

Explanation:

A founder event occurs when a small group of individuals is separated from the rest of the population, whereas a bottleneck effect occurs when most of the population is destroyed. The end result is very similar -- genetic diversity is reduced.

1.Genetic Drift is significant in small populations. ...

2.Genetic drift can cause allele frequencies to change at random. ...

3.Genetic Drift can lead to a loss of genetic variation with populations. ...

4.Genetic drift can cause harmful alleles to become fixed.
