Genome mapping in ruminants and map locations for genes influencing reproduction.
Genetic maps provide a critical link between genes and phenotypes and are essential tools in the search for the genetic basis of variation in reproductive traits. Genes coding for hormones, growth factors, receptors, binding proteins, transcription factors and enzymes that influence the development and function of the reproductive axis have been assigned to genetic maps of ruminants and locations can be found in the respective genome databases. In addition, comparative information on gene structure and map location will help define the functions of essential genes. Gene locations from other species can be used because of extensive comparative links among mammalian gene maps. Large-scale projects to sequence genes and the ability to map these genes in parallel in radiation hybrid panels of different species will greatly improve the maps and our ability to translate between them. Cloning the genes responsible for genetic differences in fertility and fecundity in ruminants is likely to provide valuable clues to understanding ovarian function and germ cell development.
