What is Sexual Dimorphism?
The ultimate source of all variation.
What is "mutations".
Hardy-Weinberg equilibrium assumes evolution is ____.
Behavior is a _______.
What is "phenotype".
Related organisms that maintain distinct set of traits in nature.
What are species?
Mate choice is not _______.
What is "conscious"?
The transfer of traits in or out of a population.
What is gene flow.
A p-value that would indicate two things are significantly different.
p < 0.05
The movement of an animal in response to the intensity of a stimulus.
Concept that defines unique species based of physical characteristics.
What is Morphological Species Concept?
The five assessments used in mate choice.
What is Courtship Behavior, Parental Care, Nuptial Feeding, Territory, Appearance?
3 forms of non-random mating.
What is Assortative Mating, Inbreeding, Self-Fertilization.
Equation for actual allele frequency.
What is the number of copies of a specific allele in a population divided by the total number for all alleles for the that gene in the population.
3 forms of learned behaviors.
What is Habituation, Associative Learning, Observational Learning.
Two requirements of speciation
What is microevolution and reproductive isolation?
3 Mechanisms of microevolution (in addition to mutation and natural selection).
What is Non-Random Mating, Gene Flow, Genetic Drift.
5 assumptions of Hardy-Weinberg Equilibrium
What is:
1. Population is infinite
2. Population is isolated
3. No new mutations
4. Random mating
5. Equal survival and reproduction
What is orientation and piloting?
3 postzygotic barriers that promote reproductive isolation.
What is reduced hybrid viability, reduced hybrid fertility, and hybrid breakdown?
Often the driver of the mating system evolution.
What are "the needs of the young".
Two specific instances of genetic drift involving small populations.
Hardy-Weinberg equation.
What is p^2 + 2pq + q^2 = 1
Two advantages of innate behavior.
What is:
Behavior is passed on to offspring, behaviors are consistent within population, zero time to exhibit behavior.
