SelectionSpeciation

Hardy Weinberg

Equilibrium

Population Genetics

Kinds of Selection


Said that populations have

the potential to grow exponentially


Who is Malthus?


Believed in inheritance of

acquired characteristics


Who is Lamarck?


Developed nearly identical theory of natural selection around the same time as Darwin


Who is Wallace?


Cuvier’s belief that periodic natural disasters wiped out large groups of

organisms that were replaced by organisms

from another region


What is catastrophism?


Believed that organisms were fixed and not

evolving and could be placed on a ladder of increasing complexity


Who is Aristotle?


Name of Darwin’s famous Publication


What is The Origin of Species by Means

of Natural Selection?


Islands where Darwin collected

samples


What are the Galapagos Islands?


Must already exist in a population for

natural selection to occur


What is variation?


Natural selection occurs at this level


What is the population level?


Phrase Darwin used to describe natural

selection


What is “descent with modification”?


Species concept that defines a

species based on physical

characteristics


What is morphological

species concept?


Type of speciation that occurs when a

population is geographically

separated


What is allopatric speciation?


Two species of moths have different

mating dances


What is behavioral isolation?


One species of flower blooms in the spring but another blooms in the fall


What is temporal isolation?


Hybrids between two species are

unable to mate and produce offspring


What is reduced hybrid fertility?


Happens when Hardy Weinberg

conditions are not met


What is evolution or change in

population gene frequency?


Represents the proportion of

dominant alleles in a population in the

HWE


What is “p”?


Equation for Hardy Weinberg

Equilibrium


What is p2 +2pq + q2 = 1?


Frequency of dominant allele in

the population where 16% show the recessive phenotype


What is 0.6?

q2 = 0.16q = 0.4

p + q = 1p = 1- q = 1- 0.4 = 0.6


Frequency of heterozygotes in a population where

64% show the dominant phenotype


What is 0.48 (or 48%)? p2 + 2pq + q2 = 1

p2 + 2pq = 0.64q2 = 1- 0.64 = 0.36q = 0.6, so p = .4

2pq = 2 * 0.6 * 0.4 = .48


All the genes in a population at a

given time


What is the gene pool?


Term for when a small population colonizes a new

habitat separating itself from the parent

population


What is the founder effect?


A localized group of interbreeding

individuals


What is a population?


Genetic exchange caused by migration

of organism or gametes into or out

of a population


What is gene flow?


Change in population gene pool because the population has been

nearly destroyed during an earthquake


What is the bottleneck effect?


Type of selection favoring two

extreme phenotypes


What is diversifying selection?


Type of selection favoring one

extreme of the phenotypic range


What is directional selection?


Type of selection favoring the most

common phenotype and selecting against

the extreme phenotypes


What is stabilizing selection?


Selection where two male mountain elk

fight for mating rights


What is intrasexual selection?


Female peacocks prefer males with brighter plumage


What is (inter)sexual selection?
