Lilla Sándorová, MSc, is a PhD student and research assistant at the Institute of Genetics and Biotechnology, Hungarian University of Agriculture and Life Sciences (MATE), Gödöllő. Her research focuses on applied animal genetics and genomics, with an emphasis on the genetic characterization of economically and biologically important traits in livestock species. Her work primarily investigates functional genetic variation in milk protein and production-related genes, with particular attention to β-casein (CSN2) polymorphisms and their population-level distribution and phenotypic relevance in dairy cattle. Using large-scale genotyping datasets, she analyses genotype–phenotype associations for milk yield and composition traits, applying mixed-effects models and population genetic approaches to distinguish statistically significant from biologically meaningful effects. In parallel, she is involved in the genetic characterization of indigenous and locally adapted livestock populations, including cattle and camel populations from African regions. These studies integrate mitochondrial and nuclear genetic markers to assess genetic diversity, population structure, and phylogenetic relationships, supporting sustainable breeding strategies and the conservation of animal genetic resources.
