Population genetic implications from sequence variation in four Y chromosome genes. De La Vega FM, Dailey D, Ziegle J, Williams J, Madden D, Gilbert DA. The observed heterozygosity of the X chromosome was 4.69 × 10-4, or 61% of the average value of the autosomes. Other influences might include selection against deleterious alleles, patterns of male dispersal35 and a correlation of diversity with recombination rate19. Nature Genet. Nature Genet.

2008 Sep 11;128(17):1951-5. To characterize the distribution of SNPs, we examined 366,192 SNPs that fell within finished sequence. 2002 Jun;Suppl:48-50, 52, 54. Tidsskr Nor Laegeforen.

The data for the heterozygosity analysis, including the coordinates of each bin, the number of bases examined and number of SNPs identified, is available as Supplementary Information. Extrapolating two exonic SNPs per gene to the approximately 30,000 human genes32, we estimate there to be 60,000 exonic SNPs in this collection. J. Mol. Google Scholar. 33). --. Work in P.Y.K.
Reads were aligned to one another and to the available genome sequence, followed by detection of single base differences using one of two validated algorithms: Polybayes24 and the neighbourhood quality standard (NQS18,22).
Shen, P. et al. SNP density (Table 1) is relatively constant across the autosomes. Humans show great variation in phenotypic traits such as height, eye color and susceptibility to disease. Article build 147, available from For the observed data, the CV (σobserved/μobserved) was 1.93, considerably larger than would be expected if every base had uniform diversity, corresponding to a Poisson sampling process (σPoisson/μPoisson = 1.73).

Two had more extreme values: chromosome 21 (π = 5.19 × 10-4) and chromosome 15 (π = 8.79 × 10-4).

The SNP Consortium, the Wellcome Trust and the National Human Genome Research Institute funded SNP discovery and data management at Cold Spring Harbor Laboratories, The Sanger Centre, Washington University in St. Louis, and the Whitehead/MIT Center for Genome Research. It is divided into two regions: a pseudoautosomal region at either telomeric end that recombines with the X chromosome and is highly heterozygous34, and the non-recombining Y (NRY). 8, 1229–1231 (1998). Prospects for whole-genome linkage disequilibrium mapping of common disease genes. Regions of known human repeats were annotated directly using RepeatMasker (A. Smit, unpublished). Copy number variation is highly correlated with differential gene expression: a pan-cancer study. Data Integrator, or Variant Annotation Integrator. Nat Clin Pract Rheumatol. To assess whether gene history would account for the observed variation in heterozygosity, we compared the observed CV to that expected under a standard coalescent population genetic model. Most human sequence variation is attributable to SNPs, with the rest attributable to insertions or deletions of one or more bases, repeat length polymorphisms and rearrangements.

More than 335 million SNPs have been found across humans from multiple populations. The CV determined under this model (σconstant-size/μconstant-size = 1.96) is a close match to the observed data. 12, 221–225 (1998).
Windows of defined size (in chromosome coordinates) were examined for whether they contained one or more SNPs. Each SNP represents a difference in a single DNA building block, called a nucleotide.
