Mitochondrial DNA and Athletic Performance in Thoroughbreds In 2006, Harrison and Turrion-Gomez reported a relationship between mitochondrial DNA (mtDNA) haplotypes and athletic performance in the Thoroughbred (Harrison & Turrion-Gomez, 2006)….
The horse karyotype Ever since the correct chromosome number in the horse was determined, the equine chromosomes have been presented in several ways. However, it was not before the correct…
Molecular biology has been crucial in refuting a central dogma in equine laminitis and in organ injury in human sepsis, stating that laminar/organ injury was due to decreased blood flow,…
Functional Impact of the Genome Genomic DNA contains the “informational blueprint” of an organism, which has now been elucidated in the horse by sequencing of the equine genome (Wade et al.,…
Application of different banding techniques A variety of staining/banding techniques have been applied to analyze equine chromosomes. The ultimate goal of using these banding techniques was to exploit a range…
Noticeable lesions indicative of the disease generally appear at approximately 1.5 years of age (White et al., 2004; White et al., 2007). This means that HERDA-affected horses rarely show signs at birth…
Cream (C) is inherited as an incompletely dominant gene. In the heterozygous condition cream dilutes phaeomelanin from red to yellow, which results in palominos, buckskins, and smoky seal browns. Homozygotes…
There is an association with a vitamin E deficiency in cases of NAD/EDM, although low vitamin E levels are not present consistently in all cases. It appears that vitamin E…
Utility of the Beadchip for Mapping Simple Traits within Breeds As a proof of principle, mapping of three known coat color loci – the recessive chestnut coat color (MC1R) (Marklund,…
For instance, the Bayesian analysis of the mtDNA data combined partial sequences from three regions: D loop, 12S rRNA, and Cytb (2074 bp total; Figure 19.1a) from Genbank and recently…
