Question

what is the founder effect?
the movement of a few individuals to a new location to start a new population
a change in allele frequency due to a dramatic loss of population
the low fitness of a select group of individuals that dont reproduce

Explanation:

The founder effect is a type of genetic drift. It occurs when a small group of individuals (founders) separates from a larger population and establishes a new population in a different location. The allele frequencies in the new population may differ from those in the original population because the founders may not carry all the alleles present in the original population in the same proportions.

• The first option describes the movement of a few individuals to start a new population, which is the essence of the founder effect.
• The second option describes a bottleneck effect (a change in allele frequency due to a dramatic loss of population).
• The third option is not a correct description of the founder effect.

Answer:

the movement of a few individuals to a new location to start a new population
