A | B |
Diploidy | 2n condition maintains and shelters alleles |
Heterozygous advantage | hereozygouts have a greater reprodutive success |
An individual who is a Sickle cell carrier (Ss) can not get malaria is an example of... | hererozgoute advanage |
Minority advantage | least comon phenotype is selected for. I.e. Drosophila wing spots |
Frequency-dependent selection | Minority advantage |
Search image | Preditors develop a standard of representation for their prey |
Evolutionary neutral traits | Traits that may posess no selective value. |
Fingerprint variation | Evolutionary neutral trait |
Genetic drift, gene flow, muitations, nonrandom mating, and natural selecion are examples of... | the causes of evolution of a population |
Genetic drift | change in the gene pool due to chance, often limiting diversity |
Bottleneck effect and founder effect | Examples of Genetic Drift |
Bottleneck effect | Natural disasters reduce a population size unselectively leaving certain alleles over or under represented. |
Tay-Sachs disease among Eastern European Jews | Bottleneck effect |
Founder effect | small population breaks away from the larger one and colonizes a new area |
Polydactyly in the Amish of Lancaster county | Founder effect. |
Gene flow | movemetn of alleles into or out of a population, often increase diversity |
Mutations | changes in getetic material and are the row material for evolutionary change |
Nonrandom mating | Individuals are not alowed to choose their mate, this may decrease the fitness of the species |
natrual selection | beter adapted to an environment survive and exhibit better repruductive success |
Hardy-Weinberg Equilibrium | Large population, isolated from other populations, no mutations, mating is random, no natural selection |
p | dominant allele (A) |
q | recessive allele (a) |
p + q = 1 | p2 +2pq+q2 = 1 |
To solve for Hardy-Weinberg always find _________ value first. | q2 or if given just q |
