Answers

population genertics - CORRECT ANSWER✔✔-the frequency of an allele
| | | | | | | | |



is NOT determined by whether it is dominant or recessive (dominant
| | | | | | | | | | |



traits aren't necessarily more frequent)
| | | |




gene pool - CORRECT ANSWER✔✔-the collection of all alleles present
| | | | | | | | | |



(for a particular gene locus) in a population
| | | | | | |




allele frequencies - CORRECT ANSWER✔✔-frequencies of particular
| | | | | | |



alleles in the gene pool
| | | |




the Hardy-Weinberg principle - CORRECT ANSWER✔✔-both genotypic
| | | | | | |



frequencies and allele frequencies remain constant over time if no
| | | | | | | | | |



micorevolution has occured | |




assumptions of the Hardy-Weinberg principle - CORRECT ANSWER✔✔-
| | | | | | |



1. no natural selection
| | |




2. random mating
| |




3. no random genetic "drift"
| | | |




4. no migration (no "gene flow")
| | | | |

, random genetic drift - CORRECT ANSWER✔✔-a change in allele
| | | | | | | | |



frequencies by chance in small populations
| | | | |




population bottlenecks - CORRECT ANSWER✔✔-genetic drift in
| | | | | | |



populations temporarily reduced to small size (overhunting)
| | | | | |




populations - CORRECT ANSWER✔✔-group of potentially interbreeding
| | | | | | |



individuals of the same species
| | | |




communities - CORRECT ANSWER✔✔-group of species sharing the
| | | | | | | |



same habitat
|




ecosystems - CORRECT ANSWER✔✔-biological and abiotic processes
| | | | | | |



and interactions within a given region
| | | | |




dispersion - CORRECT ANSWER✔✔-the locations of individuals within a
| | | | | | | | |



population
