and are capable of suffering. we would like to be able to move to a system where those same eggs are laid, but instead never hatch. scientists at the francis crick institute in london have found that the system was successful in mice, and they think it ll work on chickens. the researchers here have found a way of deactivating a gene involved with embryo development. the system can be programmed to stop either male or female embryos from developing using a technique called gene editing. the sex of a mammal is determined by its chromosomes. females have a pair of xs, males have an x and y. the process involves inserting half the gene editing molecule into the father s y chromosome, and the other half into the mother s dna. after mating, male xy embryos containing both halves of gene editing molecule will not develop. but female embryos
