Dana Liana Pusta is currently a Professor of Animal Genetics, Molecular Genetics, and Hereditary Diseases in Domestic Animals at the Faculty of Veterinary Medicine, USAMV Cluj-Napoca, Romania. She received her BSc in 1996 (veterinary medicine - FVM Cluj-Napoca), and her PhD title with "cum laude" distinction in 2005. She has published three editions of genetic textbooks for

students (two in Romanian and one in English) and more than 150 research papers. She is an EAEVE (European Association of Establishments for Veterinary Education) evaluator in the basic sciences field and she is a member of ECA (European Cytogenetics Association) and EBTNA (European Biotechnology Thematic Network Association) associations. She is co-author of two patents and 3 trademarks. She was awarded with different distinctions, such as: Diploma and Medal for the Progress of Veterinary Medicine, Best Biotechnological Product Award, and Medal of Honor of FVM Cluj-Napoca.

Genetics is a science which studies the mechanisms and biological laws that provide stability of the features during generations, meaning heredity on the one hand and the variation of

Genetics studies the three main fundamental properties of the living organisms such as hered-

The term heredity comes from Greek (gr. Hereditas), which means to inherit. Biologically, heredity refers to the inheritance of some "features and characters" from the parents to the descendants. In fact, not the characters themselves are inherited, but the potentiality of their apparition, intermediated by some material particles named genes (gr. genan = to produce, to give birth). The resulted gametes do not possess the parental characters, but they possess the parental genes which are transmitted to the future organism. The resulted zygote will form a new organism which will have particular features and characters, which will only resemble the

Basically, the characters concerning the species are inherited, but not the features which are specific to each individual. This phenomenon represents the basis of variability of the living creatures. Reproduction assures the substrate of heredity and variability of the living world,

Genetic processes are fundamental in order to understand life itself. Genetic information is stored in the DNA molecules since the formation of the first cell—the zygote, which controls all cellular functions, determines the external appearance of all organisms, and serves as a link between generations in all species. So, it is obvious that understanding of genetics is essential
