Population Genetics I: Random breeding Sue Ann Bowling Ordinary genetics looks at how one selects breeding stock to produce the best possible offspring. Population genetics looks at the statistical distribution of genes in a particular breeding population, such as a breed of dog, and how different kinds of selection can affect that gene distribution. (Increasingly, population genetics also involves looking at the relationship between species by using gene sequencing as a tool.) You can think of ordinary genetics as predicting the phenotypic makup of the next generation, while population genetics predicts the genetic makeup of the breed as a whole, often several generations away. This article is based on the assumption that the population is random breeding - an animal is equally likely to mate with any other animal in the population. This is obviously not really true - a dog in California is much more likely to mate with another California dog than with one in New York, a Great Dane is more likely to mate with another Great Dane than with a Papillion, and many breeders of domesticated animals practice deliberate breeding to relatively close relatives. We'll look at possible effects of this later on (if I get around to it). Random breeding with selection based on a single gene is the simplest case, with which other possibilities can be compared. Unfortunately, I'll have to use a little algebra to do this. I promise I'll try to explain the results in non-mathematical terms.

Population Genetics The following exercises in population genetics are designed to lead you through evolutionary experiments with a Medelian trait. The first parts examine fundamental concepts; the other parts use a simulation of the Hardy-Weinberg equilibrium and show how allelic frequencies are affected by varying genotype survival rates, initial allele percentage, and population size. This assignment is due Wednesday, October 11th,in lecture. Fundamentals A. Calculating Genotypic and Allelic Frequencies Calculate the number (not the frequency!) of each genotype in a population of 1000 individuals in Hardy-Weinberg equilibrium with an A allele frequency of 0.2; write the number of each genotype in the spaces below: No. AA = No. Aa= No. aa = Consider an initial population of 200 AA individuals, 460 Aa individuals, and 340 aa individuals. a. What are the frequencies of the alleles? Frequency of A = Frequency of a = b. Given the allele frequencies you calculated above, determine the numbers of each of the genotypes you would expect if the population were in Hardy-Weinberg equilibrium:

The Animal Mitochondrial Genome. The animal mitochondrial genome is a small, compact circular molecule that codes for 13 essential protein coding genes and the minimal translation system required to translate them: 22 tRNA genes and two rRNA genes. Since the same set of genes is present in virtually all animals, homology of these genes is clear. This observation, plus the clonal, maternal pattern of inheritance makes these genomes particularly useful for phylogenetic studies. Complete Mitochondrial Genomes. Although we cannot predict in advance what novel features may be uncovered by studying particular genomes, it is clear that the most interesting advances will come from careful analyses of complete genomes. Complete genomes provide the maximum amount of information possible for evolutionary, phylogenetic and genomic analysis. With a complete genome, we can determine whether a particular region of sequence represents the functional gene, or alternatively is a non-functional copy. Without that assurance, it can be difficult to verify unusual features. With a complete genome, we have complete information on the gene arrangement, and can compare it to that of other organisms. With complete genomes and robust phylogenies, we can make strong inferences about the evolutionary changes that have occurred in each lineage, both at the sequence and genome levels.

Population Genetics 116. Development of a genus-specific genetic marker for identification of a phytopathogenic fungus. Elisa M. Becker and William E. Hintz, University of Victoria. The basidiomycete fungus Chondrostereum purpureum is being developed as a biocontrol for forest weed species. To fulfill registration requirements we are conducting provincial and national population surveys, environmental fate studies and efficacy trials. During these studies C. purpureum as well as many other fungi are routinely isolated from wood. The mycelia of many fungi are morphologically similar on agar media and traditional biochemical tests are not specific enough to resolve fine differences, hence a PCR-generated marker that could be used to distinguish C. purpureum from other fungi was desired. Our recent work has revealed relatively little variation in the intergenic spacer region (IGS) of the ribosomal DNA (rDNA) of isolates of C. purpureum collected from several regions of the world. We hypothesized that a small portion of this region would be a good target for the design of diagnostic primers specific for C. purpureum.

Population Variability Deriving Genotypic and Allelic Frequencies Hardy-Weinberg Equilibrium Evolutionary Genetics Darwin's Theory of Natural Selection ... Genetic Topics Population variability The goal of our previous discussions in this class has been to understand the inheritance of a single trait, a trait that may be controlled by one, a few, or many genes. The goal of population genetics is different. Rather than studying the inheritance of a trait, population genetics attempts to describe how the frequency of the alleles which control the trait change over time. To study frequency changes, we analyze populations rather than individuals. Furthermore, because changes in gene frequencies are at the heart of evolution and speciation, population and evolutionary genetics are often studied together. For a population of individuals to succeed over evolutionary time, it must contain genetic variability. Because we do not know all the genetic variables that would predict evolutionary success, we study the variability of different phenotypes and genotypes to provide an overview of the population. The traits that are analyzed can be outward phenotypes that can be easily scored. More recently, biochemical and RFLP data has been used to assess population variability. This image illustrates a key concern of population genetics - the measurement of variability. This is a collection of snail shells. As you can see, many different patterns and colors are possible for the shells. Clearly many different alleles exist that control color and shape. This is an example of a polymorphic or variabile population.

EM algorithm for ABO frequencies This applet illustrates the EM algorithm for estimating allele frequencies in the ABO blood system. Users may select from a variety of sample configurations (including random allocation of phenotypes with three different sample sizes) and several different starting guesses (including random frequencies). Results from each iteration are displayed, but only six iterations can be displayed simultaenously. Genetic drift This simulation illustrates how allele frequencies change over time as a result of genetic drift in small populations. Users may select from three different starting allele frequenciese (0.1, 0.5, 0.9), five different population sizes (10, 25, 50, 100, 250), and three different numbers of generations for the simulation (50, 100, 250). Results from up to eight simulations are displayed simultaneously in different colors.

Unsourced material may be challenged and removed (July 2008) Molecular ecology is a field of evolutionary biology that is concerned with applying molecular population genetics , molecular phylogenetics, and more recently genomics to traditional ecological questions (e.g., species diagnosis, conservation and assessment of biodiversity, species-area relationships, and many questions in behavioral ecology). It is virtually synonymous with the field of "Ecological Genetics" as pioneered by Theodosius Dobzhansky E. B. Ford , and others. citation needed These fields are united in their attempt to study genetic-based questions "out in the field" as opposed to the laboratory. Molecular ecology is related to the field of Conservation genetics Methods frequently include using microsatellites to determine gene flow and hybridization between populations. The development of molecular ecology is also closely related to the use of
