This book introduces readers to classical population genetics and
the ways in which it can be applied to practical problems,
including testing for natural selection, genetic drift, genetic
differentiation, population structuring, gene flow and linkage
disequilibrium. It provides a comprehensive monograph on the topic,
addressing the theory, applications and evolutionary deductions,
which are clearly explained using experimental results. It also
offers separate chapters on origin, establishment and spread of
chromosomal aberrations in populations along with details of
culturing, maintaining and using Drosophila ananassae (genetically
unique and the most commonly used species along with D.
melanogaster) for genetic research. Encompassing topics like
genetics, evolution, Drosophila genetics, population genetics,
population structuring, natural selection and genetic drift in
considerable detail, it provides a valuable resource to
undergraduate and postgraduate students, as well as researchers at
all level. This book explores some fundamental questions concerning
the role of natural selection and genetic drift on the degree of
inversion polymorphism. India, with its wide diversity in
geo-climatic conditions, provides an excellent platform to conduct
such studies. The book showcases sampling records of inversion
frequencies in natural Indian populations of D. ananassae that
cover more than two decades. It highlights case studies in which
sampling data on inversion frequencies was combined with that from
earlier surveys, generating a time series that allows the
evolutionary dynamics of inversion polymorphism to be explored.
Such long time series are rare but nonetheless crucial for studying
the evolutionary dynamics of inversion polymorphism. The
population-genetic analysis discussed is unprecedented in terms of
its temporal (two decades) and spatial (most regions of India
covered) scale and investigates the patterns of polymorphic system
in D. ananassae to see if there is any temporal divergence. It
endeavors to present a holistic picture of inversion polymorphism
across the country (India). Chromosomal aberrations, particularly
paracentric inversions, are used as a tool for discussing
population genetic studies, helping human geneticists,
gynecologists and other medical professionals understand why some
aberrations are fatal in humans, with affected embryos often not
surviving the first trimester of pregnancy, while similar
aberrations in Drosophila flies aid in their adaptation to the
environmental heterogeneity across the globe.
