Abstract
Y chromosome analysis is used in a number of practical applications, including investigations of criminal cases, establishment of paternity, searching for missing persons, studies on human migration, evolutionary research, and historical and genealogical investigations. Questions about the origin of individual ethnic groups are addressed not only through archaeological, linguistic, and ethnographic methods but also through molecular genetics methods. The study of genetic diversity in Romania is particularly interesting from several perspectives because Romania, located in Southeast Europe, is distinguished by the fact that the Carpathians and the Danube served as natural barriers against the migrations of peoples for centuries, thus influencing the genetic mixture of the population. This is relevant for understanding the history and formation of ethnic groups in the region. In addition, many ethnic minorities live in Romania, which adds an additional dimension of genetic and cultural diversity. This article aims to provide an updated picture of the genetic diversity in Romania and to highlight the significant studies carried out among the Romanian population. By analyzing the articles published in the Web of Science, Scopus, or PubMed databases, which explore genetic diversity using the Y chromosome, the aim is to better understand the current genetic panorama in Romania.
