Genetics is currently one of the most exciting areas of scientific research and after decades of promise, the science of gene therapy, where ‘bad genes’ are removed or replaced is finally starting to deliver. This program looks at a treatment for an inherited form of blindness called Retinitis Pigmentosa ,in which a genetic mutation leads to damage of the retina and a gradual loss of sight. The treatment, which is based on correcting that mutation, will soon provide the first cure for people suffering from this form of sight loss. The video examines research comparing genetic differences between Irish and New Zealand sheep in order to increase understanding of genetics, and potentially breed Irish sheep with NZ sheep (which is currently being trialed on selected Irish farms) to improve the yield and general practice. It also considers what would happen if you could change the function of a gene, take away the gene completely, or make the gene more active through gene editing and CRISPR. The program also discusses use of gene editing to benefit crop production
