Y-chromosome variation and Irish origins
Article Abstract:
The most westerly Irish province, Connaught, is located at the geographical and genetic perimeter of a Europe-wide cline. This research involved typing 221 Y chromosomes from Irish males for seven (slowly evolving) biallelic and six (rapidly evolving) simple tandem-repeat markers. After partitioning the samples by surname, there were found to be substantial differences in genetic frequency between those of Irish Gaelic and of foreign origin, as well as between those of eastern and western Irish origin. It seems that haplogroup 1, which has a very high frequency in Ireland, is the earlier, indigenous Irish variant.

Interpreting DNA fingerprints
Article Abstract:
The US population is too heterogeneous for DNA fingerprinting to be a reliable means of legally identifying people. Surveys by the FBI and by J.R. Kidd and associates ascertained the existence several subpopulations, a finding inconsistent with population homogeneity. However, the rebuttal view is that the population substructures are not enough reason to reject DNA fingerprinting as inherently inaccurate.

On the origin of deleterious mutations
Article Abstract:
The article discusses results obtained from the various population-genetic studies that are carried out for the Americans in Europe and Africa. The unbiased genomewide count of the genetic mutations proves that the Europeans have more harmful genes, as compared to the Africans.
