(b) The relative fraction of rare alleles shared with modern Dutch compared with Spanish alleles, integrated up to allele count five in the modern samples. (nature.com)
The team uncovered strong signs of this imbalance between rare alleles and heterozygosity in two populations — one, in people living today in the Middle East, and the other in the Yakut, who live near the Bering Strait. (sciencemag.org)
Some notable conclusions from the authors include: diploids are the most fit ploidy; copy number variation (CNV) is the most prevalent type of variation; most single nucleotide polymorphisms (SNPs) are very rare alleles in the population; extensive loss of heterozygosity is observed among many strains.
