Book Synopsis Genetics, Speciation, and the Founder Principle by : Luther Val Giddings
Download or read book Genetics, Speciation, and the Founder Principle written by Luther Val Giddings and published by . This book was released on 1989 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the genetic mechanisms that govern the development and evolution of animals and plants. In particular, the book focuses on animal and plant species evolving in isolated habitats and species colonizing new territories. This approach--studying "founder" populations--enables geneticists to more readily identify some of the evolutionary pressures affecting the speciation process. The Founder Principle in population genetics was elucidated in large part by Hampton Carson in classic studies of Hawaiian fruit flies (Drosophila). The editors of this volume have commissioned seventeen chapters by an internationally recognized group of geneticists who discuss the principle in relation to plant speciation, chromosomal evolution, molecular evolution and development, sexual selection, and genetic changes in natural populations.

Available in PDF, EPUB and Kindle. Book excerpt: "During meiosis, sexually reproducing eukaryotes exchange genetic material via recombination and segregate homologous chromosomes into gametes. Surprisingly, some genes involved in meiotic recombination and chromosomal segregation experience frequent evolutionary turnover. Growing evidence suggests selfish genetic elements? DNA entities that promote their own transmission at the expense of other genes in the genome? are a significant evolutionary force driving rapid molecular evolution at genes involved in an otherwise conserved biological process. The research in this dissertation integrates classical, molecular, and population genetics to study the evolution of recombination rates and biased chromosomal segregation in Drosophila. First, in Chapters 2-4, I focus on the evolution of recombination rates in Drosophila. In Chapter 2, I perform an evolutionary screen to identify a meiosis gene with a history of recurrent positive selection that might contribute to differences in the rate of crossing over between two closely related Drosophila species. I then use a transgenic approach to show this gene, mei-217/mei-218, mediates the species differences in the rate and patterning of crossing over. In Chapter 3, I use further transgenic analyses to functionally dissect mei-217/mei-218 to determine which gene regions control the species differences in crossing over. In Chapter 4, I explore the long-term molecular evolution of mei-217/mei-218 and find evidence for frequent positive selection during the phylogenetic history of Drosophila. I find that mei-217/mei-218 wildtype alleles of two additional Drosophila species have also functionally diverged in their control of crossing over. I speculate that recurrent bouts of adaptive functional evolution at mei-217/-218 might reflect a history of coevolution with selfish genetic elements. Next, in Chapter 5, I turn to the evolution of a meiotic drive system, Segregation Distorter, that causes biased segregation in Drosophila melanogaster. I use molecular and population genetic tools to investigate the age, geographic origins, and population dynamics of Segregation Distorter chromosomes. I find that despite its stable frequency, Segregation Distorter chromosomes experience frequent selective sweeps and replacement events."--Pages xi-xii.
