Family Tree DNA: Genetic Testing Service
Many Balkan people have already taken advantage of DNA testing to learn about their connections with other families and ethnic groups, both near and far. Once you've submitted your DNA sample, you'll be eligible to join the "Romania" project if you have ancestors who lived in Romania in either or both of the genetic lines being tested. They don't limit their membership to ethnic Romanians.

Romania is a Balkan country in the lower Danube valley. It's located north of Bulgaria, southwest of Ukraine and Moldova, southeast of Hungary, and east of Serbia. Transylvania is a famous region of the country.
The much smaller Moldova is also a Romanian-speaking country and there is considerable debate about whether Moldovans are really a separate people from Romanians. I personally consider them to be the same people.
The Romanian language sounds beautiful and belongs to the Romance family in the Eastern Romance division. Once written in a form of the Cyrillic alphabet even in the 16th-19th centuries in much of Romania proper, but in Latin in Transylvania, during most of the 20th century the split was Latin in Romania proper and Cyrillic in Soviet-controlled Moldova. In 1989 Moldova switched to the Latin script, so today Romania and Moldova both use the same writing system.
In comparison with other European ethnic groups, it is comparatively hard
(as of 2012) to find detailed data on Romanian DNA.
Nevertheless, I was able to find the following estimates for the frequencies
of Y-DNA haplogroups among Romanian people:
22.2% I or I2
Haplogroup I is also common in Bosnia and Herzegovina, in Serbia, in Croatia, in Sardinia, and in Scandinavian countries. Some of these peoples, especially Sardinians and Serbs, are believed to primarily descend from among the earliest European settlers, prior to successive waves of new immigrations from the Near East.
Haplogroup I2a1b is found in especially high frequencies in northeastern Romania, Moldova, and central Ukraine.
I tried to parse out ethnic Romanians in Family Tree DNA's "Romania" group. As far as I can tell, for non-Jewish non-Hungarian non-German non-Roma ethnic Romanians their Y-DNA haplogroups include E1b1b1, G, I1, I2a, Q, and R1b1a2. This is in line with the expectations from the frequencies above. Their mtDNA haplogroups include H, H7, I, J, K1c1, M, U4, and U5.

"Population history of the Dniester-Carpathians: evidence from Alu markers." Journal of Human Genetics 52:4 (2007): pages 308-316. First published electronically on February 16, 2007. Based on Alexandru Varzari's dissertation "Population History of the Dniester-Carpathians: Evidence from Alu Insertion and Y-Chromosome Polymorphisms" for the Faculty of Biology Ludwig-Maximilians-Universität on July 27, 2006. Abstract:
"The area between the Dniester and the eastern Carpathian mountain range is at a geographical crossroads between eastern Europe and the Balkans. Little is known about the genetics of the population of this region. We performed an analysis of 12 binary autosomal markers in samples from six Dniester-Carpathian populations: two Moldavian, one Romanian, one Ukrainian and two Gagauz populations. The results were compared with gene frequency data from culturally and linguistically related populations from Southeast Europe and Central Asia. Small genetic differences were found among southeastern European populations (in particular those of the Dniester-Carpathian region). The observed homogeneity suggests either a very recent common ancestry of all southeastern European populations or strong gene flow between them. Despite this low level of differentiation, tree reconstruction and principle component analyses allowed a distinction between Balkan-Carpathian (Macedonians, Romanians, Moldavians, Ukrainians and Gagauzes) and eastern Mediterranean (Turks, Greeks and Albanians) population groups. The genetic affinities among Dniester-Carpathian and southeastern European populations do not reflect their linguistic relationships. The results indicate that the ethnic and genetic differentiations occurred in these regions to a considerable extent independently of each other. In particular, Gagauzes, a Turkic-speaking population, show closer affinities to their geographical neighbors than to other Turkic populations."

"[...] The results of our study provided an additional support for the existence of limited maternal gene flow between eastern Asia/southern Siberia and eastern Europe revealed by analysis of modern and ancient mtDNAs previously [...] It is noteworthy that another eastern Asian specific lineage, C5c1, revealed exclusively in some European populations (Poles, Belorussians, Romanians), shows evolutionary ages within frames of 6.6-11.8 kya depending on the mutation rates values . [...] Prehistoric migrations associated with the distribution of the pottery-making tradition initially emerged in the forest-steppe belt of northern Eurasia starting at about 16 kya and spread to the west to reach the south-eastern confines of eastern European Plain by about 8 kya  could be suggested as a potential cause for eastern Asian mtDNA haplogroups appearance in Europe.

"A striking feature of the samples used for this study is how well the geographic origin of the samples appears to correlate with the genetic origin, so that separating the samples by country of origin or on the basis of genetic measures gives similar results. The only major deviation from this pattern is with the Romanian samples that appear to be closer to the Spanish samples (further 'west') than their geographic position would indicate. This could be because of the historical close ties between Romania and Italy, but further studies would be required to confirm this."

Romanian Society of Legal Medicine 12:4 (2004): pages 239-246. To what degree, if any, are the ancient Thracian people related to modern-day Romanians? That was a goal of this study. Excerpts:
"We have performed a study of mtDNA polymorphisms (HVR I and HVR II sequences) on the skeletal remains of some old Thracian populations from SE of Romania, dating from the Bronze and Iron Age in order to show their contribution to the foundation of the modern Romanian genetic pool and the degree of their genetic kinships with other old and modern human European populations. [...] Computing the frequency of common point mutations of the present-day European population with the Thracian population has resulted that the Italian (7.9%), the Albanian (6.3%) and the Greek (5.8%) have shown a bias of closer genetic kinship with the Thracian individuals than the Romanian and Bulgarian individuals (only 4.2%). [...] So far we can just suppose, that the old Thracian populations would have been able to contribute to the foundation of the Romanian modern genetic pool. More mtDNA sequences from Thracian individuals are needed in order to perform an complex objective statistical analysis."

Excerpts from the Abstract: "Our genetic study was focused on old human populations from the Bronze and Iron Ages from Romania [...] Concerning the genetic relationships at mitochondrial level, old human populations from Romania have shown closer genetic relationship to Turks of Thracian origin, while modern Romanians were closer to modern Bulgarian, Italian, Greek and Spanish populations."

Science 343:6172 (February 14, 2014): pages 747-751. Companion website. In analyzing the genetics of 13 Romanian people, the team detected an admixture event that occurred sometime around the year 1054, and almost certainly between 886 and 1194. One part of their ancestry is related to peoples like Lithuanians and Finns while the other part is related to peoples like Greeks, Cypriots, and Southern Italians including Sicilians.
