Population Genetics and [Evolution]
Gene pool
set of all genes or genetic information in particular species
Allele Frequency
Number of copies of an allele in population/Total number of all alleles for that gene in population
Genotype Frequency
Number of individuals with particular genotype in population/Total number of individual in population
Hardy -Weinberg Principle or Equilibrium
States that allele and genotype frequency remain same in generation to generation if there is no evolutionary influence
Assumption of Hardy -Weinberg Equilibrium
No Migration
No Mutation
No large population
No selection
No random matching
Microevolution
evolutionary change in allele frequency of species over short time
Factors
Mutation
change in genetic sequence
Natural selection
individual organism that posses favorable traits are most likely to survive and reproduce
Genetic drift
overall shift of allele distribution in an isolated population due to random fluctuation in individual allele of gene
Migration
Non random mating
Population Genetics
study of genetic variation within population
