Random Change

The human male specific Y-chromosome passes from father to son essentially unchanged, but occasionally a random change, known as a mutation, occurs. These mutations, also called markers, serve as beacons and can be mapped. When geneticists identify a mutation in a DNA test, they try to determine when it first occurred and in which part of the world. Thus, the Y-chromosome haplogroup, which is a population group descended from a common ancestor, can be used to trace the paternal lines of men. The poster describes a research project that aims to identify the ancient geographical origins of key ethnic communities of the Indian subcontinent, based on their Y-DNA haplogroups.

AbstractVietnam exhibits great cultural and linguistic diversity, yet the genetic history of Vietnamese populations remains poorly understood. Previous studies focused mostly on the majority Kinh group, and thus the genetic diversity of the many other groups has not yet been investigated. Here we analyze complete mtDNA genome sequences and ~2.3 Mb sequences of the male-specific portion of the Y chromosome from the Kinh and 16 minority populations, encompassing all five language families present in Vietnam. We find highly variable levels of diversity within and between groups that do not correlate with either geography or language family. In particular, the Mang and Sila have undergone recent, independent bottlenecks, while the majority group, Kinh, exhibits low levels of differentiation with other groups. The two Austronesian-speaking groups, Giarai and Ede, show a potential impact of matrilocality on their patterns of variation. Overall, we find that isolation, coupled with limited contact involving some groups, has been the major factor influencing the genetic structure of Vietnamese populations, and that there is substantial genetic diversity that is not represented by the Kinh.

AbstractVietnam exhibits great cultural and linguistic diversity, yet the genetic history of Vietnamese populations remains poorly understood. Previous studies focused mostly on the majority Kinh group, and thus the genetic diversity of the many other groups has not yet been investigated. Here we analyze complete mtDNA genome sequences and 2.34 mB sequences of the male-specific portion of the Y chromosome from the Kinh and 16 minority populations, encompassing all five language families present in Vietnam. We find highly variable levels of diversity within and between groups that do not correlate with either geography or language family. In particular, the Mang and Sila have undergone recent, independent bottlenecks, while the majority group, Kinh, exhibits low levels of differentiation with other groups.

Colonial Singapore witnessed the movement and settling of Chinese, Malay, Indian, Arab, European and other mercantile groups as a free port and emporium of the British Empire. This social landscape was defined by boundaries between the different ethnic communities, often drawn up by the British, in contrast to the cosmopolitan exchanges of the market. This article focuses on the Indian business communities which had played a significant role in maritime trade networks since pre-colonial times and continued to be a part of Singapore's developing society and economy in the British period. A minority in the colonial era port city and largely confined within intra-ethnic economic and social circuits, Indians participated in the complex colonial structure of trade and credit alongside British, European and Asian traders and merchant houses, as brokers, agents, and retailers. British hegemony over the Indian subcontinent was both an advantage and a disadvantage for these Indian trading communities. This article brings to light the history of Indian networks in the colonial transnational flows of capital and entrepreneurship, and their patterns of integration into and role in the development of Singapore, a role marginalised in the scholarship and the national narratives alike by a focus on the large-scale Indian labour migrations.
