Genetic progress in cattle: a global overview

With the arrival of gene editing, there have been several recent developments in cattle genetics, with many more expected. Gene editing allows breeding programmes to introduce desired changes in a controlled way and at a more rapid pace than is possible using only conventional selection. As Dr Alison van Eenennaam explains that gene editing involves guiding enzymatic DNA ‘scissors’ to do a targeted, specific cut at a predetermined DNA sequence.
