BEIJING, China — Have you been longing for a “teacup” pig but worried that your pet might grow as big as your bathtub?
A Chinese company says it now has the answer: a swine that would weigh no more than about 33 pounds fully grown. The company, called BGI, created the pigs by changing their DNA, which contains the instructions for how each cell in the body works. DNA is passed on from parents to children.
