Review General Biology 1
Chapter 15 How Organisms evolve
Define Population,
What is a population level phenomenon?
Define phenotypic plasticity. How does mutation help phenotypic plasticity?
How do genes and environment interact to produce a phenotype?
Define genotype, phenotype, gene, DNA, locus, nucleotide, allele, heterozygous, homozygous. How are they all related?
What is population genetics?
What is the ‘gene pool’?
What is meant by ‘allele frequency? How is evolution related to allele frequency?
Define ‘equilibrium population’, Hardy Weinberg Principle.
What does the Hardy Weinberg principle do?
What are the conditions describe by Hardy Weinberg?
Define each of these and explain how each of these impacts evolution.
Mutations, Gene flow, small populations, random mating and natural selection.
Define and explain genetic drift and its effects on evolution; population bottle neck; founder effect;
What is the evolutionary definition of ‘fitness’?
What are the forces for evolution?
How is Natural Selection really Differential reproduction?
What does ‘fit’ mean?
Describe: directional selection; stabilizing selection; disruptive selection – give examples.
What is the ‘normal curve’? which is the ‘norm’, which are the extremes? What does it mean?
What is ‘balanced polymorphism’?
How do adaptations help an individual to survive and reproduce?
Define Abiotic, biotic. Give examples of each.
How do they affect survival and reproduction?
Define Resource Competition; CoEvolution; Symbiosis; Parasitism; Commensalism; Mutualism; Give examples of each.
What is meant by Sexual selection?
Define and give examples of Altruism; Kin selection; Inclusive fitness
What are the two parts of inclusive fitness?
Not all scientists believe in altruism or kin selection – why? What arguments support the theory?
