This is the course of under graduate level about the population genetics. Population genetics is a subfield of genetics that deals with genetic differences within and between populations, and is a part of evolutionary biology. Studies in this branch of biology examine such phenomena as adaptationspeciation, and population structure. Population genetics was a vital ingredient in the emergence of the modern evolutionary synthesis. Traditionally a highly mathematical discipline, modern population genetics encompasses theoretical, lab, and field work. Population genetic models are used both for statistical inference from DNA sequence data and for proof/disproof of concept. What sets population genetics apart today from newer, more phenotypic approaches to modelling evolution, such as evolutionary game theory and adaptive dynamics, is its emphasis on genetic phenomena. The course provides the students theoretical and practical knowledge of the population genetics. Students practically and theoretically trained for getting better genotype in the next generation. This course will help students gain an insight into the latest techniques for livestock improvement through genetics.

Theory

Gene and genotypic frequency; Hardy-Weinberg law; forces affecting gene frequency and composition of population, effective population size; Quantitative characters and their inheritance; Biometrical concepts in population genetics;  measures of central tendency and dispersion for quantitative traits; Basic theorems of additively of variance, regression and correlation concepts; Nature and causes of variation in quantitative traits and partitioning of hereditary variance; Concepts of heritability and repeatability and methods of their estimation; Genetic and phenotypic correlations; Genetic basis and causes of variation.

Practical

Exercises on gene and genotypic frequencies in random mating populations. Numerical exercises on the estimation of various statistical parameters and hypothesis testing using computers. Exercises on the estimation of heritabilities, repeatabilities and genetic correlation from given data. Case studies for lethal, semi-lethal and other genetic abnormalities in farm animals.
