Evolution Flashcards
What does the Hardy-Weinberg Equation assume (5)?
- No mutations. 2. No migration. 3. Very large population size. 4. Random Mating. 5. No natural selection.
What is the Hardy-Weinberg Equation?
(p^2)+2pq+(q^2)=1. RR+Rr+rr=1.
Does genetic drift increase or reduce genetic variation?
Reduces.
What is the Hardy-Weinberg Law?
Frequencies of alleles in a population’s gene pool remain constant, or at equilibrium, from generation to generation unless acted upon by agents other than sexual recombination.
If the Hardy-Weinberg assumptions are met, then what can we assume?
There is no evolution occurring.
What is genetic drift? In what kinds of populations does it have more of an effect?
A change in the gene pool as a result of chance. It has more of an effect on smaller populations.
What are 2 examples of genetic drift?
- Founder effect. 2. Bottleneck effect.
Species with more or less genetic variability are more likely to survive in a changing environment?
More.
