5Stabilizing selection _______________ the mean trait value and reduces variation in the trait.
- Aincreases
- Bmaintains
- Creduces
6[blank_start]Stabilizing[blank_end] selection maintains the meant trait value and [blank_start]reduces[blank_end] the variation in the trait.
- AStabilizing
- Breduces
7Disruptive selection occurs when the tails of the distribution are not favored over the intermediate phenotypes.
- AVerdadero
- BFalso
8What type of selection is this?
- Adirectional
9Genetic drift, gene flow, and mutation pressures are other ways in which evolution may occur.
- AVerdadero
- BFalso
10Genetic drift, gene flow, and mutation pressures only enhance selection.
- AVerdadero
- BFalso
11Genetic drift isn't Darwinian evolution, correct?
- Acorrect
- Bincorrect
12A fixed allele, with a frequency of 1, is the only allele in that population.
- AVerdadero
- BFalso
13Label the Y axis
- Afitness
- Bmean fitness
- Cmean allele frequency
14Why type of evolution can get a population from point X to point Y?
- Anatural selection
- Bgenetic drift
15Immigration is always good.
- AVerdadero
- BFalso
16Horizontal gene transfer is when genes from one species are introduced into another organism compared to vertical (parent to offspring) transmission.
- AVerdadero
- BFalso
17Horizontal gene transfer....
- Aallows for rapid acquisition of traits
- Bmore common among eukarya
- Cmore common among bacteria
- Dslows down the acquisition of traits
18Modern [blank_start]Synthesis[blank_end] demonstrated that [blank_start]natural[blank_end] selection operating on Mendelian variation could lead to rates of evolutionary changes that explain historical patterns of evolution.
- ASynthesis
- Bnatural
19What equation allows evolution to be documented and qualified? [blank_start]HW[blank_end]
- AHW
20Hardy-Weinberg Theroem serves as a null hypothesis for whether evolution is occurring in a population. It assumes...
- Asmall population
- Blarge population
- Crandom mating
- Devery genotype has the same probability of mating
- Eimmigration
- Fno immigration
- Gemigration
- Hno emigration
- Iequal fitness
- Jmutations
21HW assumptions are important because any [blank_start]violation[blank_end] is a way that [blank_start]evolution[blank_end] can occur.
- Aviolation
- Bevolution
22If a difference of frequency is found between the actual and expected alleles/genotypes, then evolution has occurred/
- AVerdadero
- BFalso
23You should practice the math questions at the end of this powerpoint.
- AVerdadero
- BFalso
