A regular egg is compared to one that has quadruple yolks at a house in Xi’an, Northwest China’s Shaanxi province, Aug 17, 2015. A woman cracked eggs to cook and surprisingly found one with four yolks. The egg was a standard size but the yolks were smaller. The woman didn’t cook the special egg and kept it in her refrigerator. The odds of discovering a four-yolker are eleven billion to one, according to experts. Liu Kai, a US-educated biology PhD, says the quadruple-yolked egg is, in all ways other than the number of yolks, the same as a normal egg. (Photo/CFP)
