Microevolution

Question 1

What is microevolution

Answer 1

change in the allele frequent in population over time

Question 2

what is macroevolution

Answer 2

large-scale patterns in evolution, like species formation

Question 3

what are the five mechanisms of microevolutions

Answer 3

Natural selection
gene flow
genetic drift
mutation
artificial selection

Question 4

What are the three main causes of evolutionary change

Answer 4

Genetic drift
gene flow
natural selection

Question 5

what is gene flow

Answer 5

where a population may gain or lose alleles when fertile individuals move into or out of population

Question 6

What does gene flow reduce between populations?

Answer 6

differences

Question 7

What is genetic drift?

Answer 7

chance events causing allele frequencies to fluctuate unpredictably from one generation to the next

Question 8

What would be an example of a genetic drift?

Answer 8

An iceberg when penguins on it breaking off from rest of population

Question 9

Would a genetic drift have a larger impact in a large population or a small one?

Answer 9

a small population

Question 10

What is the founder effect?

Answer 10

a few individuals colonize an island or other new habitat

Question 11

What is the Hardy-Weinberg Equation

Answer 11

p^2+2pq+q^2 = 1

Question 12

what is p and q in the hardy-weinberg equation?

Answer 12

p = frequency of dom allele
q = frequency of recessive allele

Question 13

What the main conditions that must be present for the Hardy-Weinberg equation to work?

Answer 13

a very large population
no gene flow between populations
no mutations
random mating
no natural selection
