  • Molecular parentage analysis using microsatellite marker


My name is Viktoriia and I am originally from Ukraine. I completed my bachelor and master study in Kharkiv State Zoo Veterinary Academy. Presently I am doing a Ph.D in University of South Bohemia in České Budějovice and simultaneously I started a research work in Laboratory of Gene Expression, Institute of Biotechnology CAS. The topic of my Ph.D study is “Polyspermy produces viable haploid/diploid mosaics in sturgeon”. As known, the majority of sturgeon species are critically endangered and at the same time they are producers the most expensive luxury roe – black caviar. So, my Ph.D study describes a unique fertilization pattern in detail and refutes statements that polyspermy is fatal for Acipenseridae family. Obtained data in this research can help to avoid negative effect on sturgeon propagation programs; is useful for the correct ploidy determination in sturgeon species and opens a new opportunity for biotechnology research to establish sturgeon clone mass production. Out of work my interests are: bicycle riding, attending of swimming pool, drawing and travelling.
