    Pig linkage map [Sus scrofa; Breed=G�ttingen miniature, Meishan].
    Taxonomy ID=9823
    A Japaanese pig map using a boar of Göttingen miniature pig and two sows of Meishan pig as parents. In the construction of the family, two F1 males and 18 F1 females were intercrossed to generate 143 F2 offspring. The linkage maps of all the chromosomes except for chromosome 1 were found to be longer in females than in males. Concerning chromosome 1, the length of the linkage map showed no difference between females and males, which was attributed to low recombination rates between markers localized in the centromeric region in females. The average ratio of female-to-male recombination was calculated to be 1.55.. Available from ARKDB.

    Horse linkage map [Equus caballus; Breed=(mixed; n/a)].
    Taxonomy ID=9796
    A comprehensive male linkage map was generated by adding 359 new, informative microsatellites to the International Equine Gene Map half-sibling reference families and by combining genotype data from three independent mapping resources: a full sibling family created at the Animal Health Trust in Newmarket, United Kingdom, eight half-sibling families from Sweden and two half-sibling families from the University of California, Davis. The map was constructed from a total of 766 markers distributed on the 31 equine chromosomes.. Available from DOI.

    An improved chicken consensus linkage map with 12,945 SNPs on the Wageningen (WU), East Lansing (EL), and Uppsala (UPP) mapping populations. The resolution of the chicken consensus linkage map has been dramatically improved in this study by genotyping 12,945 single nucleotide polymorphisms (SNPs) on three existing mapping populations in chicken: the Wageningen (WU), East Lansing (EL), and Uppsala (UPP) mapping populations. The current map consists of 34 linkage groups and covers at least 29 of the 38 autosomes.. Available from PUBLICATION.

  1. One "reference map" per species was chosen based on the availability, marker density, and popularities in terms how they are used in QTL studies at the time (roughly from mid-1990s to 2010s).
  2. "None reference map" information was used when reported as an underlining map in the QTL analysis. The map locations were interpolated to the default map of the species during data curation process.
  3. Curated data map locations are on reference maps only.
