본문내용

*Population Genetics
The study of evolution from a genetic point of view
Composed of numerous individuals of a certain species interbreeding routinely.
The smallest unit of the evolution
Microevolution : a change in the collective genetic material in population
Equals to the change in the collective group of a variety of alleles in which each individuals contain

*Bell Curve
Observable traits of individuals also varies within the same population
May be drawn as a graph statistically
Bell Curve : the bell-like shape of a graph which represents the frequency of a certain observable traits within the population
x-axis : the variation of the trait
y-axis : the frequency of the number of individuals showing the trait
In fact, it is of normal distribution
The most of the individuals show the average trait
The most representative variation for numerous quantitative traits
