Photo by Jon Chase For the first time, sets of closely linked genetic markers have been cataloged for researchers who want to conduct genomewide searches for common genetic influences on disease, according to a flurry of papers published by researchers including (from left) Stephen Schaffner, Pardis Sabeti, and Paul de Bakker. For the first time, a relatively small and affordable sampling of the human genome can provide the means to track down the many slight differences in genes that conspire to cause type 2 diabetes or explain why an antihypertensive drug lowers blood pressure in one person but causes a devastating side effect in another. The same resource can reveal genes that have been important in recent human evolutionary history.

Extractions: CLICK HERE TO RETURN TO THE EXERCISE Knowledge Test Questions on Population Biology and Coevolution 1. What is a population and what is population genetics? A population is a group of individuals from the same species that occupy the same geographic region and exhibit reproductive continuity from generation to generation. Populations are often defined based on geographical boundaries or evidence for genetic exchange. Population genetics is a subdiscipline of genetics that seeks to understand and explain the processes that lead to the creation and maintenance of genetic variation within populations of organisms. 2. Why is population biology important for plant pathologists? Pathogens exist as dynamic populations that change, or evolve, through time and space. Effective disease control requires control of a population of individuals and not simply an individual. Knowledge of population biology is needed to implement sustainable disease management practices. 3. What is coevolution?

Population = a group of interbreeding individuals of the same species sharing a common geographical area C. Species = a group of populations that have the potential to interbreed in nature and produce viable offspring D. Gene pool = sum total of all the alleles within a population E. Four processes of evolution mutation - changes in nucleotide sequences of DNA. Mutations provide new alleles, and therefore are the ultimate source of variation recombination natural selection - differential reproduction (discussed below) reproductive isolation (discussed shortly) F. Mutation and recombination provide natural variation , the raw material for evolution.

Extractions: Population genetics is the study of the distribution of and change in allele frequencies under the influence of the four evolutionary forces: natural selection genetic drift mutation and migration . It also takes account of population subdivision and population structure in space. As such, it is the theory that 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 Ronald Fisher , who also laid the foundations for the related discipline of quantitative genetics Contents showTocToggle("show","hide") 1 Scope and theoretical considerations

Extractions: POPULATION GENETICS: LIMITS TO ADAPTATION Introduction: Organisms are generally assumed to exhibit traits that are adaptive to the specifics of the environment in which they are found, as a result of natural selection. Some studies have indicated, however, that certain traits appear to be maladaptive, yet they are maintained within a population. This maladaptation may be a result of genetic constraints (such as a trait that is genetically correlated with another trait that is changing under selection), recent or fluctuating changes in selective pressures, conflicts between natural selection and sexual selection (for example, the long tail feathers of male peacocks), or gene flow (the movement of genes between two or more populations). The latter is the focus of this module. Importance: The role of gene flow in limiting adaptation has been debated by biologists. However there is evidence from field and lab experiments to indicate that gene flow can be an important factor, and may help explain the persistence of maladaptive traits in some populations. Question: How is gene flow measured? What conclusions can be drawn from these measurements?

Contact Us You are here : The BDS Research Population Genetics Population Genetics of Sika Deer To establish whether the Purbeck populations are pure Sika or hybrids. DNA samples taken from different sika populations within the Isle of Purbeck will be challenged with a number of genetic "probes" to look for a number of marker genes which we know to be possessed only by red deer, or only by sika deer. Pure sika populations should have only sika marker genes, and none characteristic of red deer. Hybrid populations will show a combination of characteristically 'red' and characteristically 'sika' genes (Goodman et al., 1999). Simon Goodman has agreed to make available to us the same probes as he himself used in his own studies of hybridisation in Scottish populations. To establish whether populations of Sika deer from different parts of Purbeck are genetically distinct and thus isolated or part of a continuous population. In order to explore the degree of relatedness between different subpopulations within Purbeck, the sample of sika above will be drawn from ten different subpopulations across the Isle of Purbeck (Figure 1). Thirty animals will be sampled from each sub population (approximately 15 males and 15 females per subpopulation).

Extractions: A two factor mutation-selection process suggests an algorithm of the general form Gt +M(Gt)+ S(Gmt)=Gt+k. where M(Gt) is the impact of mutation operations on the initial population of genes and S(Gmt) is the impact of selection operations on the gene pool modified by mutation. By tradition, the change from Gt to Gt+k is depicted as an iterative process involving successive generations or cycles of mutation and selection. Multiple decrement mathematics suggests that analyzing changes in a large complex distributions can be reduced to or divided into analysis of the components of the population. The analysis of the composition of a gene pool can thus be reduced to the analysis of changes in the frequency of individual alleles. For an individual allele Ax, the two factor change model becomes- Axt + M(Axt) + S(Axmt)=Axt+k. A common misconception is that because the incremental process M is weak- produces only a very small increase in the probability of Ax- the offsetting decrement process can also be weak. Contrary to what might at first seem intuitive, it requires a very strong 100% force of decrement to offset even a weak force of increment and maintain a 0% end of cycle distribution. Even a very strong force of decrement, a 99% decrement for example, result in a small but steady increase in the frequency of Ax in the population. The absence of Ax in the population therefore leads to the conclusion that the force of decrement applicable to Ax is 100%. Either 1)the allele Ax is fatal, 2)the allele from which Ax mutates is essential to existence, or 3)the biological system contains some mechanism for completely suppressing Ax.
