The main objective of the project is to detect, analyze and identify through different molecular-cytogenetic methodologies the chromosomal alterations relating to changes in the chromosome number or aneuploidy, produced in our autochthonous Andalusian cattle breeds endangered during the process In Vitro Fertilization (IVF) in both sperm and in the oocytes and the embryo itself. The aims is to answer a series of questions with which every day many researchers who study them, as the reason for the low fertility of our autochthonous endangered cattle breeds or what happens in their germ cells to make this happen. A review of the published studies carried out in many other breeds, with no particularities of our breeds, showed very few information to give us satisfactory answers, finding in them a great diversity and disparity that we think there are not applied to our breeds because of their own characteristics. We try in this project to combine all existing techniques in the fields of production, reproduction and genetics, and develop and put in place other that we can really know what happens and at the same time allowing to help to farmers in their efforts to maintain and breeding the autochthonous breeds that, we can not forget, have a fundamental value which is to enable the sustainable development in the production areas.
