population
!
100
define gene flow
What is Transfer of alleles into or out of a population.
100
define founders effect
occurs when a few individuals become isolated from a larger population
100
Chance events causing allele frequencies to fluctuate unpredictably from one generation to the next, particularly in small populations.
What is genetic drift
100
is the study of genes, heredity, and genetic variation in living organisms.
What is Genetics
100
is a statistical formula that basically states; if you give me the frequency of genes in a population, I will tell you the frequency of individuals in a population.
What is Hardy-Weinberg theorem
200
the stock of different genes in an interbreeding population.
What is Gene pool
200
Discuss the concept of genetic variation within populations and how such variation influences the range of phenotype in a population. How is variation beneficial to a population?
What is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
200
define mutation
What is This is the actual change in the genetic code
200
changes in allele frequencies in a population
What is Microevolution
200
heterozygote genotype has a higher relative fitness than either the homozygote dominant or homozygote recessive genotype.
What is heterozygote advantage
300
define nonrandom mating
occurs when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals.
300
Is all genetic variation adaptive?
no, only natural selection
300
Increased vigor or other superior qualities arising from the crossbreeding of genetically different plants or animals.
What is hybrid vigor
300
How does the modern evolutionary synthesis integrate Darwinism?
What is Modern evolution just states that gradual changes are still taking place right now but they might take billions of years to see the physical changes.
300
favors individuals at both extremes of the phenotypic range
What is disruptive selection
400
A group of individuals of the same species that live in the same area and interbreed
What is Population
400
is the term given to an evolutionary process where the fitness of a phenotype is dependent on its frequency relative to other phenotypes in a given population.
What is frequency-dependent selection
400
Group of actually or potentially interbreeding natural populations (individuals) which can and will interbreed to produce fertile offspring.
What is species
400
Identify factors on which naural selection acts.
What is Variation exists within a species. Species overproduce. Competition exists. Inheritance.
400
favors intermediate variants and acts against extreme phenotypes
What is stabilizing selection
500
breed from closely related people or animals, especially over many generations.
What is inbreeding
500
is a sudden and drastic reduction in population size due to a change in the environment
What is bottleneck effect
500
this is the only one that improves the match between an organism and the environment. In the blue eye example, does that improve the populations best fit? Not likely. Some sort of tolerance, camouflage, weapon or defense.
What is natural selection
500
Explain the concept that natural selection can not fashion the perfect organism.
What is trade offs - Changing one feature for the better might change another for the worse
500
favors individuals at one end of the phenotypic.
What is directional selection
