Population Genetics and Evolution Introduction In 1908, G.H.Hardy and W. Weinberg independently suggested a scheme whereby evolution could be viewed as changes in frequency of alleles in a population of organisms. In this scheme, if A and a are alleles for a particular gene locus and each diploid individual has two such loci, then p can be designated as the frequency of the A allele and q as the frequency of the a allele. For example, in a population of 100 individuals ( each with two loci ) in which 40% of the alleles are A, p would be 0.40. The rest of the alleles would be ( 60%) would be a and q would be equal to 0.60. p + q = 1 These are referred to as allele frequencies . The frequency of the possible diploid combinations of these alleles ( AA, Aa, aa ) is expressed as p +2pq +q Hardy and Weinberg also argued that if 5 conditions are met, the population's alleles and genotype frequencies will remain constant from generation to generation. These conditions are as follows: The breeding population is large. ( Reduces the problem of genetic drift.)

Next: The Measurement of Up: Molecular markers of zooplankton Previous: Introduction Fundamental Science: Population Genetics of Marine Zooplankton The disciplinary roots for the analysis of dispersal across a species' distributional range lie in a central dogma of population ecology: where N is the number of individuals at a given time ( t ) and after some interval ( t+1 B is the number of births, D is the number of deaths, and I and E are the numbers of individuals immigrating and emigrating, respectively. Dispersal is quantified by assessing the immigration and emigration of individuals among conspecific populations. The dispersal of marine zooplankton can be inferred from the population genetic structure of a species by statistical analyses developed by population genetic theory (see Wright ] for a comprehensive treatment). To do this, the frequencies of individual traits are determined for geographic populations of a species, and analyzed by the statistical approaches of population genetics. The use of genetic characters to examine population structure and patterns of gene flow has been an active area of research for many years (see reviews by Avise ] and Wilson et al ]). Genetic approaches may help to resolve long-standing questions about the dispersal of zooplankton in the ocean. Genetic characters have the advantage that they are unambiguous identifiers of an individual or lineage, but a population genetic approach will yield statistical rather than deterministic conclusions about the dynamics of zooplankton populations in the ocean. Population genetics, despite the term, is a study of individual characteristics and cannot be done using groups (or pooled individuals). It is unlikely that it will be possible to predict an individual zooplankton's destination, but it may be possible to determine the proportion of immigrant individuals in a given region on an oceanographically relevant time scale.

89. The Value Of Population Genetics To The Breeder The Value of population genetics to the Breeder by John Armstrong. Asa breeder, you are a practicing geneticist. To breed effectively http://www.netpets.com/dogs/reference/genetics/popgen.html

The Value of Population Genetics to the Breeder by John Armstrong As a breeder, you are a practicing geneticist. To breed effectively you need to know something about genetic principles. (Would you sit down to a bridge game expecting to win without any knowledge of the rules?) What is often called "Mendelian genetics" deals with the outcome of specific crosses. Population genetics deals with the distribution of alleles in a population and the effects of mutation, selection, inbreeding, etc. on this distribution. A knowledge of both is critical not only to your own success, but also to the survival of your breed. Once-upon-a-time, many geneticists believed that there were only two alternatives for a gene - "good" alleles that functioned normally and "bad" alleles that didn't. If things were this simple, then the task of the geneticist-breeder would be simplified to one of identifying the bad alleles and trying to eliminate them from the population. Such a simplistic model could be modified to allow for different "good" alleles, but it should not matter whether you have one or another. These early geneticists expected to find little genetic variability in a population. The majority of individuals were expected to be homozygous for the good allele for most genes. With the advent of modern biochemical and molecular tools, geneticists studying populations found far more variability (diversity) than they had expected. There are a number of possible reasons for this, and even the experts are not in total agreement on the most likely reason(s). However, geneticists have also discovered that populations lacking genetic diversity often have significant problems and are at greater risk from disease and other changes in their environment. The conclusion is that genetic diversity is desirable for the health and long-term survival of a population.

However, fisheries managers do not typically receive training in population genetics. This is due, in large part, to lack of course materials in population genetics relevant to fisheries science. Few fisheries students go forward with courses focusing on genetics of fruit flies, corn, or humans, and even when they do, the applications of principles to problems they will face in their careers often are unclear. The availability of a textbook for a course in fisheries genetics would make the field of population genetics relevant and accessible to students and practitioners of fisheries science. Qualified instructors too busy to develop their own course from scratch could use the book as a ready resource for teaching such a course. This book was born of a need perceived by many fisheries geneticists.

This volume collects 57 of Kimura's most important papers and covers forty years of his diverse and original contributions to our understanding of how genetic variation affects evolutionary change. Kimura's neutral theory, first presented in 1968, challenged the notion that natural selection was the sole directive force in evolution. Arguing that mutations and random drift account for variations at the level of DNA and amino acids, Kimura advanced a theory of evolutionary change that was strongly challenged at first and that eventually earned the respect and interest of evolutionary biologists throughout the world. This volume includes the seminal papers on the neutral theory, as well as many others that cover such topics as population structure, variable selection intensity, the genetics of quantitative characters, inbreeding systems, and reversibility of changes by random drift.

The in Vienna, Austria, will be funding a program on Mathematical Population Genetics and Statistical Physics from December 2002 to February 2003. Organizers: Ellen Baake, Greifswald Michael Baake, Greifswald General information Programs at the ESI are intended to bring together leading scientists working in a field and give them the opportunity of collaborating here in Vienna for a couple of weeks.The main focus of this program will be on multilocus genetics, on stochastic processes in population genetics, and on the relations to statistical physics and applied mathematics. The main purpose is, of course, to foster interaction among participants, thus providing the possibility of advancing research in this field and breaking new ground. In addition, two workshops will be held: one from 16 December 2002 - 20 December 2002 the other from 17 February 2003 - 21 February 2003 Background and scope of this program Population genetics seeks to describe biological evolution at the level of gene-frequency changes in populations. Its mathematical tools have been developed since the beginning of the 20th century; they are thus young if compared to mathematical physics, but highly developed if compared with most other fields of theoretical biology, which are much younger. This program shall be focused on two branches that are interrelated, mathematically highly developed, and of great biological interest: multilocus genetics and its applications to phenotypic evolution, and stochastic processes relevant in molecular genetics and related fields.

POPULATION GENETICS OF MOUSE LEMURS In addition to investigations of Madagascar's biogeographic past, we are also concerned with the accelerating environmental crisis in Madagascar and its effect on the extant biota. Virtually all of Madagascar's mammals, for example, are severely threatened by environmental destruction. Perhaps the single exception to this pattern is the mouse lemur (genus Microcebus ). As the world's smallest living primate and as an ecological generalist, it thrives in the secondary growth that results from deforestation. We are employing phylogenetic and population-genetic techniques to assess the history and taxonomic diversity of several western populations of the mouse lemur. The aims of this research are twofold. In collaboration with M. Rodin RASOLOARISON and Dr. Jorg Ganzhorn, we are investigating the correlation between morphological and geographic distinctions observed among these populations and the deep genetic divergences apparent within the mitochondrial data. This correlation implies that taxonomic diversity in these populations, currently described as a single species M.murinus
