Microevolution

Question 1

What is microevolution?

Answer 1

A change in allele frequencies within a population

Question 2

Define Alleles

Answer 2

alternative forms of the same gene “flavors”

arise from differences in DNA sequence

Question 3

Define population

Answer 3

Population is a group of localized individuals capable of interbreeding and producing fertile offspring

Question 4

what are the 3 mechanisms of microevolution?

Answer 4

1. Natural selection
2. Genetic drift
3. Genetic flow

Question 5

Define Natural selection

Answer 5

Natural selection in the process by which certain traits become more or less common.

Question 6

Define Genetic drift

Answer 6

• Changes in allele in population due to randomness
• -> May cause alleles to dissapear
• Founder effect
• Bottleneck

Question 7

Define Genetic flow

Answer 7

Is that transfer of alleles from one population to another 
through
-reproduction
-pollen
-horizontal gene transfer
--can reduce homogenize fitness

Question 8

What are the differences b/w macro and microevolution?

Answer 8

-Microevolution occurs in a smaller scale within a population but macroevolution occurs @ species level (ecologically)
