Population Genetics and Evolution
Heredity
passes on traits
controlled by genes
Phenotype
bell-shaped curve
Genotype
evolution happens by variation
mutation
errors in DNA replication
viruses
Radiation
Mutagens
transposons
recombination
independent assortment
Mechanism of evolution
natural selection
Genetic drift
founder effect
population bottleneck
Gene flow
hybridization
migration
based on ideas of
Charles Darwin
theory of evolution
Gregor Mendel
model of inheritance
segregration
dominance
independent assortment
James watson and crick
structure of DNA
Carolus Linnaeus
classification of organism
group of individuals of same species in same area
Gene pool
common group of genes
Relative allelic frequency of an allele
Gene shuffling
happens during meiosis
crossing over
happens during prophase I
Hardy- Weinberg principle
Allele frequencies in a population must remain constant
no selection
large population
random mating
no migration
no mutation
Types of isolation
Behavioral
occurs when capable of interbreeding
Geographical
no mating due to physical barrier
Temporal
reproduce different times of he year
Genetic Drift
Random changes in allelic frequency in small populaions
