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 p...

Embryo development. the system can be programmed to stop either male orfemale 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 a 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 the gene—editing molecule will not develop, but female embryos will grow normally. gene editing can be used to make other genetic changes. these piglets are ...

Pallab ghosh reports. half of these chicks are useless to the farming industry because they're male and don't lay eggs, so they have to be killed. that problem could be solved thanks to a breakthrough that enables scientists to reprogramme animals to produce only females. some 6 to 7 billion male layer chicks are killed every year shortly after birth at a point when they have a nervous system 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...
