Molecular genetics as a diagnostic tool in farm animals.
In this review, the importance of molecular genetics for diagnostic applications in animal production and breeding is underlined. Recently, several new techniques and methods based on gene technology have been developed, such as the polymerase chain reaction, fluorescence in situ hybridization, and the use of microsatellite polymorphism. The examples include detection of favourable alleles of genes coding for milk proteins, recognition of negative recessive alleles in hereditary syndromes, the use of microsatellite variants for breeding purposes and parentage control, and application of specific DNA-probes for identification of Y-chromosome-bearing spermatozoa and the sex of embryos. It is to be understood that this list is not complete and more applications will undoubtedly show up in the future. For this review, the authors have mainly selected areas where they themselves or their co-workers have gained experience.
