|
Definition
|
|
Term
| What does the Hardy-Qeinberg principle predict? |
|
Definition
1)The frequency of alleles;
2)Will stay constant from one generation to the next/no genetic change over time;
3)Providing no mutation; |
|
|
Term
| What conditions have to be meet in order to apply the Hardy-Weinberg Principle? |
|
Definition
-No mutation
-No selection
-Large population
-Population genetically isolated
-Mating at random
-No migration |
|
|
Term
|
Definition
| where both alleles are equally dominant |
|
|
Term
| Define Directional Selection |
|
Definition
| When selection may favour individuals that vary in one direction from the mean of the population. |

Term
| Explain what is meant by a recessive allele |
|
Definition
| Only expressed when homozygous |
|
|
Term
| Explain what is meant by codominant alleles |
|
Definition
| Both alleles are expressed |
|
|
Term
| Explain Geographical Isolation |
|
Definition
1) Separate gene pools
2) Different environment conditions
3) Selection for different alleles
4) Differential reproductive success
5) Leads to change in allele frequency |
