This container track contains annotation tracks with individual level genotypes, usually phased, and tracks where only the variant frequencies, aka allele frequencies, are shown. The tracks were collected from the following projects. Only the projects 1000 Genomes (its own track), HGDP, SGDP, HGDP+1k and MXB provide individual-level genotypes. All others provide only allele frequencies, their genotypes require signing a data access agreement.
++Available on hg19 and hg38:
+Available only on hg38:
+Most tracks only show the variant and allele frequencies on mouseover or clicks. When zoomed in, tracks display alleles with base-specific coloring. Homozygote data are shown as one letter, while heterozygotes will be displayed with both letters.

This can be +Full haplotype display - only for the MXB and HGDP tracks: +In "pack" mode, this track sorts the haplotypes. This can be useful for determining the similarity between the samples and inferring inheritance at a particular locus. -For a full description of how the display works, please see our -Haplotype Display help page. -Briefly, each sample's phased and/or homozygous genotypes are split into haplotypes, +Each sample's phased and/or homozygous genotypes are split into haplotypes, clustered by similarity around a central variant (in pink), and sorted for display by their position in the clustering tree. Click a variant to center on it. The tree (as space allows) is drawn in the label area next to the track image. Leaf clusters, in which all haplotypes are identical (at least for the variants used in clustering), are colored purple.

Most of the data in these tracks are not available for download from UCSC. Only individual variants can be browsed on our website. But the data can be downloaded for free from the original projects. Accessing the data usually requires a click-through license on the respectice websites:
-MXB: Allele frequencies by geographical state and ancestry are available via +MXB: Allele frequencies by geographical state and ancestry are available via the MexVar platform. Raw genotype data are available under controlled access at the EGA (Study: EGAS00001005797; Dataset: EGAD00010002361). For the VCFs, email andres.moreno@cinvestav.mx.

-MXB: Genotyping was performed with the Illumina Multi-Ethnic Global Array +MXB: Genotyping was performed with the Illumina Multi-Ethnic Global Array (MEGA, ~1.8M SNPs), optimized for admixed populations and enriched for ancestry-informative and medically relevant variants. Only autosomal, biallelic SNPs passing quality control are included. Samples were selected from 898 recruitment sites, with prioritization of indigenous language speakers. Data processing included GenomeStudio → PLINK conversion, strand alignment, removal of duplicates, update of map positions using dbSNP Build 151 and low-quality variants/individuals, and relatedness filtering.
-SGDP: The version used was +SGDP: The version used was https://sharehost.hms.harvard.edu/genetics/reich_lab/sgdp/vcf_variants/, merged with bcftools and lifted to hg38 with CrossMap.
