genetic drift

Question 1

define genetic drift

Answer 1

the change in allele frequencies as a result of the chance process

Question 2

which population is more susceptible?

Answer 2

smaller populations

- a greater chance that the allele will be lost

Question 3

what are the two types of genetic drift?

Answer 3

1) founder effect

2) bottleneck population

Question 4

what is the founder effect?

Answer 4

• occurs when a new colony is started by a few members of the original populations
• small population that branches off from a larger o

Question 5

what is the bottleneck population?

Answer 5

• Occurs when a population undergoes an event in which a significant % of a population or species is killed or otherwise prevented from reproducing
• Can eliminate alleles entirely or also cause other alleles to be overrepresented in a gene pool

Question 6

what is a bottleneck?

Answer 6

any kind of event that reduces population significantly
