Term
If a bird from a population of AA birds travels to a population of aa birds and introduces the AA allele there, what is this called? |
|
Definition
Gene flow- the movement of allele's from one population to another. |
|
|
Term
What does gene flow cause? |
|
Definition
It keeps differing populations similar and increases the variations in populations. |
|
|
Term
If a hurricane destroys eighty-five percent of the population on an island and the fifteen percent that are left survived by chance, what if this called? |
|
Definition
Genetic Drift-changes in gene pool due to chance (not natural selection) |
|
|
Term
What is geographic isolation and is there any gene flow in geographic isolation? |
|
Definition
Geographic isolation is when mountains, rivers, oceans, and/or (but not limited to) canyons separate population. There is no gene flow. |
|
|
Term
What is the founder effect? |
|
Definition
This is the genetic drift that occurs when a small number of individuals colonize a new area. |
|
|
Term
What is it called when organisms aren't geographically isolated by can't reproduce because of different mating rituals and the use of pheromones? |
|
Definition
|
|
Term
If two organisms are unable to reproduce because they have different mating seasons and one organisms is nocturnal, what is this called? |
|
Definition
|
|
Term
What is the end result of behavioral, geographical, and temporal isolation? |
|
Definition
Reproductive isolation. Two organisms that are unable to reproduce with each other, species. |
|
|
Term
What are the five factors that can lead to evolution? |
|
Definition
Genetic drift, Gene flow, Mutation, sexual selection, and natural selection. (GGMSN) |
