Genome analysis helps in breeding more robust cows

Genome analysis of 234 bulls has put researchers on the trail of DNA variants which influence particular characteristics in breeding bulls. For example, two variants have proven responsible for disruptions to the development of embryos and for curly hair, which is disadvantageous because more ticks and parasites occur in curly hair than in short, straight hair. These are the first results of the large 1000 Bull Genomes project on which some 30 international researchers are collaborating.
