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.

Seed samples from 19 stands of Larixoccidentalis Nutt. were analyzed for electrophoretic variation at 23 loci. Because sample sizes consisted of only 9 or 10 trees per stand (18–20 alleles per locus per stand), samples were grouped by geographic proximity into four larger samples. For all measures of variation, this species scored lower than most, but within the range observed for other western conifers. Most of the variation was found within rather than between the population groups. The single southern sample appeared to be genetically distinct from the others. Although some variation was observed between individual stand samples in expected heterozygosity, the consistently low values for all samples suggest that genetic drift has played a major role in the genetic history of the species in the Inland Empire, both through its glacial history in postulated refugia and through fire history in recent times.
