A microarray is a set of samples, for example DNA, RNA or proteins, arranged on a solid substrate or chip, such as a glass slide or silicon film, that is used in high throughput experiments. Microarrays enable multiple simultaneous measurements to be made in one experiment.
An analysis of the population genetic structure of Newfoundland and Labrador identifies close genetic links between this population and South England and South Ireland, with a strong bottleneck roughly 300 years ago.
