Welcome to PopGen 1.0 1. What is PopGen PopGen is a simulation program designed to clarify various population genetic events. It is aimed mainly for teaching purposes. It has been programmed by Jouni Aspi using Microsoft's Visual Basic. The code is based on previous GW-Basic and QuickBasic programs by Jaakko Lumme and Jouni Aspi. 2. General description With PopGen you can simulate some deterministic and stochastic population genetic processes in a simple one locus, two allele system. There are two alleles A1 and A2. Frequency of allele A1 is p and frequency of allele A2 is q. Genotypes of individuals and their frequencies are: Genotype A A A A A A Frequency p q With the models of PopGen you can study how these allele frequencies are affected by: Genetic drift Selection Migration You can also study sample sizes you need to detect significant deviations from Hardy-Weinberg proportions, when: The studied population is divided to two subpopulations 2. Allele frequencies are not similar in different sexes 3. The mating is not random, but there is some inbreeding in the population 3. Download PopGen for Windows is now available for Windows 3.x and Windows'95. See

22. The Gene School - Population Genetics The more genes two animals have in common, the closer they are related (not by blood, but by evolution) to one http://library.thinkquest.org/19037/population.html

Population Genetics The level of species can be further divided into smaller segments. A population is the smallest unit of a species and is made up of organisms of the same species. All the hemlock trees in a forest make up a population of hemlock trees, and all the rattlesnakes on an island make up a population of rattlesnakes, and so forth. Sometimes, a population will physically alter over time to suit the needs of its environment. This is called a cline, and can make members of the same species look different. A subspecies is a distinct population of a species. A good example of a subspecies is the western flicker which has red wings and looks different than the eastern flicker which has yellow wings. The two types of birds belong to the same species, though, because they can produce fertile offspring (sometimes with orange wings!).

Site Map Population genetics Resources A natural bacterial population, showing a range of size and morphology Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. Many of the genes found within a population will be polymorphic - that is, they will occur in a number of different forms (or alleles ). Mathematical models are used to investigate and predict the occurrence of specific alleles or combinations of alleles in populations, based on developments in the molecular understanding of genetics, Mendel's laws of inheritance and modern evolutionary theory. The focus is the population or the species - not the individual. The collection of all the alleles of all of the genes found within a freely interbreeding population is known as the gene pool of the population. Each member of the population receives its alleles from other members of the gene pool (its parents) and passes them on to other members of the gene pool (its offspring). Population genetics is the study of the

Genetics Genetic Epidemiology Evolution Biostatistics ... Homepage BASIC POPULATION GENETICS M.Tevfik Dorak, M.D., Ph.D G.H. Hardy (the English mathematician) and W. Weinberg (the German physician) independently worked out the mathematical basis of population genetics in 1908 ( Hardy, 1908 ). Their formula predicts the expected genotype frequencies using the allele frequencies in a diploid Mendelian population. They were concerned with questions like "what happens to the frequencies of alleles in a population over time?" and "would you expect to see alleles disappear or become more frequent over time?" Hardy and Weinberg showed in the following manner that if the population is very large and random mating is taking place, allele frequencies remain unchanged (or in equilibrium) over time unless some other factors intervene. If the frequencies of allele A and a (of a biallelic locus) are p and q, then (p + q) = 1. This means (p + q) = 1 too. It is also correct that (p + q) = p + 2pq +q = 1. In this formula, p

It also takes account of population subdivision and population structure in space. As such, it attempts to explain such phenomena as adaptation and speciation . Population genetics was a vital ingredient in the modern evolutionary synthesis , its primary founders were Sewall Wright J. B. S. Haldane and R. A. Fisher , who also laid the foundations for the related discipline of quantitative genetics Scope and theoretical considerations Perhaps the most significant "formal" achievement of the modern evolutionary synthesis has been the framework of mathematical population genetics. Indeed some authors (Beatty 1986) would argue that it does define the core of the modern synthesis.

Population Genetics Overview Alleles of a gene don't all exist at an equal frequency within a population. Some alleles are far more common than others, and these frequencies may change over time in response to external forces. Population genetics studies the frequencies of alleles within a population, and the probabilities of inheriting a particular trait based on those frequencies. This branch of genetics also looks at the forces that can affect allele frequency. Objectives Know the meanings of the terms 'population' and 'gene pool'. Understand that not all alleles are present at equal frequencies within a population. Know what the Hardy-Weinberg principle states, know the Hardy-Weinberg equation, and be able to use the equation to calculate the allele frequencies of the next generation of a population (to determine if the population is in equilibrium). Know the factors that can affect allele frequency, and how they affect allele frequency. Up to this point in the course, we have used the principles of genetics to calculate the probabilities of an individual inheriting a particular trait from its parents. What we didn't consider in such calculations is how frequently such a trait might occur in an entire

Diploid organisms will have two potential alleles for any particular stretch (gene, sensu latu ) of DNA (e.g., a 'normal' and a 'mutant' allele for Drosophila trait such as eye color). If the alleles are the same (or indistinguishable) on both chromosomes, the individual is a homozygote, if the alleles differ, a heterozygote. Bateson and Saunders (1902) originally coined the term for traits alternative to one another in Mendelian inheritance (Gk. Allelon , one another; morphe , form). Now used for alternative forms at a genetic locus Codominant alleles are particularly useful as genetic markers Allopatric: having non-overlapping geographic ranges. Cf. sympatric Allozymes Codominant protein variants ( alleles ) that can be visualized by appropriate staining and starch-gel electrophoresis . These were the first major molecular genetic markers Assignment (test): A method of assigning individuals to the populations from which they were most likely to have originated (regardless of where they dispersed to or were sampled).
