Identification and characterization of an AFLP marker associated with carcass composition in the pig (Brief report)

Abstract. Amplified Fragment Length Polymorphism (AFLP) is a DNA fingerprinting technique that allows genotyping of DNA polymorphisms, mainly single nucleotide substitutions (SNP), across the whole genome with high multiplex ratio and without the need of their prior knowledge. We have successfully combined AFLP with selective genotyping for mapping of quantitative trait loci (QTL) in a F₂ resource population based on Duroc and Berlin Miniature pig (DUMI) (WIMMERS et al., 2002). Here we report application of this approach for the identification of loci associated with carcass composition in a herd of commercial German Landrace pigs.
