TLDR
This map provides the skeletal framework prerequisite to development of a comprehensive genetic map for cattle and analysis of economic trait loci (ETL).Abstract:
We report the most extensive physically anchored linkage map for cattle produced to date. Three-hundred thirteen genetic markers ordered in 30 linkage groups, anchored to 24 autosomal chromosomes (n = 29), the X and Y chromosomes, four unanchored syntenic groups and two unassigned linkage groups spanning 2464 cM of the bovine genome are summarized. The map also assigns 19 type I loci to specific chromosomes and/or syntenic groups and four cosmid clones containing informative microsatellites to chromosomes 13, 25 and 29 anchoring syntenic groups U11, U7 and U8, respectively. This map provides the skeletal framework prerequisite to development of a comprehensive genetic map for cattle and analysis of economic trait loci (ETL).read more

The Calpain System
TL;DR: How calpain activity is regulated in cells is still unclear, but the calpains ostensibly participate in a variety of cellular processes including remodeling of cytoskeletal/membrane attachments, different signal transduction pathways, and apoptosis.

Parasite-mediated selection against inbred Soay sheep in a free-living, island population
TL;DR: It is shown that relatively inbred Soay sheep (Ovis aries) are more susceptible to parasitism by gastrointestinal nematodes, with interactions indicating greatest susceptibility among adult sheep at high population density, and it is suggested that parasite‐mediated selection acts to maintain genetic variation in this small island population by removing less heterozygous individuals.

Abundance, variability and chromosomal location of microsatellites in wheat.
Marion S. Röder,Jens Plaschke,Susanne U. König,Andreas Börner,Mark E. Sorrells,Steven D. Tanksley,Martin W. Ganal +6 more
TL;DR: It was found that wheat microsatellites are relatively long containing up to 40 dinucleotide repeats, and more variation was detected with the micros satellite markers than with RFLP markers with, on average, 4.6 different alleles per microsatellite.

Mapping Quantitative Trait Loci Controlling Milk Production in Dairy Cattle by Exploiting Progeny Testing
Michel Georges,Dahlia M. Nielsen,Margaret J. Mackinnon,A. Mishra,Ronald Okimoto,A. T. Pasquino,L S Sargeant,A. Sorensen,M R Steele,X. Zhao +9 more
TL;DR: These findings demonstrate that loci with considerable effects on milk production are still segregating in highly selected populations and pave the way toward marker-assisted selection in dairy cattle breeding.

TL;DR: Two new methods were used to establish a rapid and highly sensitive prenatal diagnostic test for sickle cell anemia, using primer-mediated enzymatic amplification of specific beta-globin target sequences in genomic DNA, resulting in the exponential increase of target DNA copies.

The estimation of map distances from recombination values.
TL;DR: The genetic map is a tool to quantify the distance between genes on a chromosome, based on the observed frequency of crossovers during cell division, which is used to estimate the total distance between chromosomes.

Rapid and sensitive detection of point mutations and DNA polymorphisms using the polymerase chain reaction
TL;DR: It is found that most single base changes in up to 200-base fragments could be detected as mobility shifts and the interspersed repetitive sequences of human, Alu repeats are highly polymorphic.
