Fisheries management is getting difficult due to over utilization of fish stocks, pollution and various human activities resulting reduction of genetic resources and variations. Therefore, molecular genetic studies of natural population is dependent on the polymorphic neutral markers and offer the possibility of investigation of population structure and provide scientific data for regulation of...

About 40 years ago, scientists first strongly advocated the integration of population ecology and population genetics into population biology (Singh and Uyenoyama, 2004). Even today these two disciplines are not really integrated, but there is a general appreciation of population genetic con­ cepts in population ecology and vice versa. For example, the new subdiscipline molecular ecology, and m...

Some introductory genetics: Genes are DNA sequences whose code determines which proteins are produced, and are grouped together in chromosomes. Higher organisms have two copies of each chromosome, one from the male and one from the female; such organisms are referred to as diploid. Thus each organism has two, possibly different, copies of each gene (these copies of a gene are called alleles). T...

Molecular population genetics aims to explain genetic variation and molecular evolution from population genetics principles. The field was born 50 years ago with the first measures of genetic variation in allozyme loci, continued with the nucleotide sequencing era, and is currently in the era of population genomics. During this period, molecular population genetics has been revolutionized by pr...

These lecture notes introduce key concepts of mathematical population genetics within the most elementary setting and describe a few recent applications to microbial evolution experiments. Pointers to the literature for further reading are provided, and some of the derivations are left as exercises for the reader.

Microbial Population Genetics // 190445559X, 9781904455592 // Jianping Xu // 213 pages // Horizon Scientific Press, 2010 // 2010 Microbial population genetics is a rapidly advancing field of investigation with relevance to many areas of science. The subject encompasses theoretical issues, such as the origins and evolution of species, sex, and recombination. Population genetics lays the foundati...

Cancer is a complex disease of the genome that arises from the interplay of numerous underlying biological processes occurring within and between cells. Cancer population genetics aims at investigating malignant dynamics by studying the distribution of somatic alterations in cancer cell populations. Such aberrant DNA modifi cations lead to the development of cellular malignant traits like cance...

Population genetics investigates the distribution of genetic variation in natural populations and the genetic differentiation among populations. Lichen-forming fungi are exciting subjects for population genetic studies due to their obligate symbiosis with a green-algal and/or cyanobacterial photobiont, and because their different reproductive strategies could influence fungal genetic structures...
