Coalescent Theory: An Introduction

A considerable number of human diseases can be attributed to genetics, from simple Mendelian diseases like sickle-cell anemia and cystic fibrosisto more complicated maladies like cancers and coalesdent illnesses. Coalescent theory can also be used to model the amount of variation in DNA sequences expected from genetic drift and mutation.

The mathematical theory of the coalescent was developed independently by several groups in the early s as a natural extension of classical population genetics theory and models [1] [2] [3] [4]but can be primarily attributed to John Kingman. An algorithm for morphological phylogenetic analysis with inapplicable data.

Coalescent theory can be used to make inferences about population genetic parameters, such as migration, population size and recombination.

Therefore, although the expected time to coalescence is 2 N eactual coalescence times have a wide range of variation. The utility of coalescent theory in the mapping of disease is slowly gaining more appreciation; although the application of the theory is still in its infancy, there are a number of researchers who coalescrnt actively developing algorithms for the analysis of human genetic data that utilise coalescent theory.

Coalescent theory – Wikipedia

Note that coalescent time is the number of coalesceng generations where the coalescence took place and not calendar time, though an estimation of the latter can be made multiplying 2 N e with the average time between generations.

Population genetics Statistical genetics. Mathematical and Conceptual Foundations. It is immensely useful in understanding coalescenf diseases and their processes to know where they are located on chromosomesand how they have been inherited through generations of a family, as can be accomplished through coalescent analysis [1].

In a population with coaescent constant effective population size with 2 N e copies of each locus, coaescent are 2 N e “potential parents” in the previous generation.

Both regular the coalescent and the shattered coalescent which allows that multiple mutations may have occurred in the founding event, and that the disease may occasionally be triggered by environmental factors have been put to work in understanding disease genes [1]. His research has focussed on populations structured by geography and limited migration.

Email alerts Wa,ely issue alert. The 2 important points to take from these facts are that, first, coalescent theory is still an active and exciting topic that continues to be developed in its fundamentals and applications and, second, that any book on coalescent theory is going to be heavy on the mathematics. Molecular Biology and Evolution 31 5: Andrea Piazzi marked it as to-read Sep 27, The above calculations apply equally to a diploid population of effective size N e in other words, for a non-recombining segment of DNA, each chromosome can be treated as equivalent to an independent haploid individual; in the absence of inbreeding, sister chromosomes in a single individual are no more closely related than two chromosomes randomly sampled from the population.

The theory was initially developed by Kingman in 3 papers published in probability theory journals, which outline the foundation of coalescent theory as a suite of probability models. These traits may arise due to many small mutations, which together have a severe and deleterious effect on the health of the individual [2].

The model looks backward in time, merging alleles into a single ancestral copy according to a random process in coalescence events. A model for tracing the history of genetic variation.
