A genetic map of Ovis aries (haploid n = 27) was developed with 519 markers (504 microsatellites) spanning ∼3063 cM in 26 autosomal linkage groups and 127 cM (female specific) of the X Chromosome (Chr). Genotypic data were merged from the IMF flock (Crawford et al., Genetics 140, 703, 1995) and the USDA mapping flock. Seventy-three percent (370/504) of the microsatellite markers on the map are common to the USDA-ARS MARC cattle linkage map, with 27 of the common markers derived from sheep. The… 
A male linkage map constructed for QTL mapping in Spanish Churra sheep.
This map represents an approximate 90% coverage of the autosomal ovine genome and constitutes a useful tool for the genetic dissection of complex traits in this breed.
A meiotic linkage map of the silver fox, aligned and compared to the canine genome.
The first meiotic linkage map of the fox genome is constructed, which provides a critical tool for genetic studies in foxes and identification of genetic loci and genes implicated in fox domestication.
A radiation hybrid map of sheep chromosome 23 based on ovine BAC-end sequences.
Evidence is presented for the usefulness of ovine BES when constructing a high-resolution comprehensive map for a single sheep chromosome and the constructed RH map demonstrates the resolution and utility of the newly constructed ovine RH panel.
A second generation genetic map for rainbow trout (Oncorhynchus mykiss)
A second generation genetic map for rainbow trout is constructed using microsatellite markers to facilitate the identification of quantitative trait loci for traits affecting aquaculture production efficiency and the extraction of comparative information from the genome sequences of model fish species.
Molecular Cytogenetics and Gene Mapping in Sheep (Ovis aries, 2n = 54)
The selective expansion of the sheep cytogenetic map, using loci to connect maps and identify chromosome bands, can substantially contribute to improving the quality of the annotated sheep genome sequence and will also accelerate its assembly.
Genetic monitoring of a Santa Ines herd using microsatellite markers near or linked to the sheep MHC
There was a reduction in heterozygosity over the years in relation to the whole population, and the Ovar-MHC region of chromosome 20 was shown to be highly polymorphic.
Genetic diversity in Asblack sheep (Ovis aries) of Lima, Peru by microsatellite markers.
A high genetic diversity was found in the populations studied by breed and individuals, with a moderate differentiation of Asblack sheep with its parental breeds, a result supported by the factorial correspondence analysis.
Comparative mapping of sheep chromosome 2q
Twenty-six genes from HSA2q (2q21.1→2q36) have been assigned to OAR2q by genetic linkage mapping to refine this area of the sheep genome.
Mapping quantitative trait loci (QTL) in sheep. I. A new male framework linkage map and QTL for growth rate and body weight
A custom maximum likelihood program was developed to map QTL in half-sib families for non-inbred strains (QTL-MLE) and is freely available on request and offers the advantage of enabling QTL × fixed effect interactions to be included in the model.
Associations of alleles of 13 microsatelite loci located on sheep chromosome 20 (Major Histocompatibility Complex) with performance and carcass traits as well as resistance to gastrointestinal parasites in 138 pure Santa Ines sheep and their crosses with Bergamasca, Texel and Ile de France are observed.


A comprehensive map of the porcine genome.
The high-resolution comprehensive map has the marker density needed to identify quantitative trait loci (QTL), implement marker-assisted selection or introgression and YAC contig construction or chromosomal microdissection.
An autosomal genetic linkage map of the sheep genome.
We report the first extensive ovine genetic linkage map covering 2070 cM of the sheep genome. The map was generated from the linkage analysis of 246 polymorphic markers, in nine three-generation
Cosmid-derived markers anchoring the bovine genetic map to the physical map
Comparison of the estimated size of the physical and linkage maps suggests that the genetic length of the bovine genome may be around 4000 cM.
A genetic linkage map of the bovine genome
A cattle genetic linkage map was constructed which marks about 90% of the expected length of the cattle genome and shows as many differences in gene order compared to humans as is found between humans and mice.
A genetic linkage map for cattle.
This map provides the skeletal framework prerequisite to development of a comprehensive genetic map for cattle and analysis of economic trait loci (ETL).
A medium-density genetic linkage map of the bovine genome
A cattle genetic linkage map was constructed which provides a basis for high-resolution mapping of the bovine genome with physical resources such as Yeast and Bacterial Artificial Chromosomes as well as providing the underpinning for the interpolation of information from the Human Genome Project.
Directed cosmid isolation of bovine markers for physical assignment by fish
A directed PCR‐based iterative screening protocol was developed to isolate cosmids containing microsatellite markers linked to chromosomal regions of interest, such as those near the ends of linkage groups or quantitative trait loci, and may be extended to comparative mapping of genes.
Comparative mapping of human Chromosome 2 identifies segments of conserved synteny near the bovine mh locus
Overall, the data reveal a complex rearrangement of gene order between BTA2q12-44 and HSA2q14-37 that underscores the need to establish boundaries of conserved synteny when applying comparative mapping information to identify genes or traits of interest.
Meiosis and spermatogenesis in bulls heterozygous for a presumptive 1/29 Robertsonian translocation.
Bulls heterozygous for the 1/29 Robertsonian translocation showed normal mating behaviour, semen quality and spermatogenesis. The karyotypes of 90 offspring of one heterozygous bull were consistent
Convergent Domestication of Cereal Crops by Independent Mutations at Corresponding Genetic Loci
This work has shown that independent domestication of sorghum, rice, and maize involved convergent selection for large seeds, reduced disarticulation of the mature inflorescence, and daylength-insensitive flowering, which supports models of quantitative inheritance that invoke relatively few genes, obviates difficulties in map-based cloning of QTLs, and impels the comparative mapping of complex pheno-types across large evolutionary distances.
