Overview In simpler terms, Evolutionary Genetics is the study to understand how genetic variation leads to evolutionary change.  Evolutionary Genetics attempts to account for evolution in terms of changes in gene and genotype frequencies within populations and the processes that convert the variation with populations into more or less permanent variation between species.  The central challenge of Evolutionary Genetics is to describe how the evolutionary forces shape the patterns of biodiversity.  Evolutionary Genetics majorly deals with; a. Evolution of genome structure b. The genetic basis of speciation and adaptation c. Genetic change in response to selection within populations ]]>

Basics of Undergraduate/university fellows Nucleosome model of chromosome is proposed by ROGER KORNBERG (son of Arthur Kornberg) in 1974.  It was confirmed and crystalised by P. Oudet et al., (1975).  Nucleosome is the lowest level of Chromosome organization in eukaryotic cells.  Nucleosome model is a scientific model which explains the organization of DNA and associated proteins in the chromosomes.  Nucleosome model also explains the exact mechanism of the folding of DNA in thenucleus.  It is the most accepted model of chromatin organization.]]>

Basics of Undergraduate/university fellows Epistasis is a Greek word that means standing over.  BATESON used term epistasis to describe the masking effect in 1909  The term epistasis describes a certain relationship between genes, where an allele of one gene hides or masks the visible output or phenotype of another gene.  When two different genes which are not alleles, both affect the same character in such a way that the expression of one masks (inhibits or suppresses) the expression of the other gene, the phenomenon is said to be epistasis.  The gene that suppresses other gene expression is known as Epistatic gene.  The gene that is suppressed or remain obscure is called Hypostatic gene  The classical phenotypic ratio of 9:3:3:1 F2 ratio becomes modified by epistasis.]]>
