One of the three Chinese pigs bred in 2006 has given birth to eleven piglets after mating with a normal boar. Two of the piglets inherited the gene for Green Fluorescent Protein from the mother.

“The mouths, trotters and tongues of the two piglets glow green under ultraviolet light, which indicates the technology to breed transgenic pigs via cell nuclear transfer is mature,” Liu Zhonghua, a professor at Northeast Agricultural University in Harbin, capital of Heilongjiang province, was quoted as saying.
