Kaydon and Layton Wood are just five yet already they are local celebrities. In fact, the twins have been making headlines in regional newspapers since they were born – because one is white and the other black. Kaydon 和Layton Wood仅仅只有五岁，但是他们已经是当地的名人了。实际上，这对双胞胎一出生就出现在在地区资讯头条，因为他们的一个是白皮肤，一个却是黑皮肤。 Each year, 12,000 sets of twins are born in Britain. Of these, 385 of them are black or mixed race, but those like Kaydon and Layton are rare. 英国每年有12000对双胞胎出生，其中385对是黑色或混血种族。但是像Kaydon 和Layton Wood这样的非常稀少. Dr Jim Wilson, a population geneticist at the University of Edinburgh, explains: “Since parents contribute 50 per cent of the genes each to an offspring, the first generation born to a mixed-race couple will definitely be midway in colour between the two. But second-generation children are different. If one of the offspring marries a white person, it is possible for them to have a white child. It is not certain actually. One child in ten is now mixed race, which potentially means black and white twins will become far more common. ” 爱丁堡大学人口遗传学家Jim Wilson博士解释说：“父母对后代各占50%的遗传基因，第一代混血儿在肤色上肯定会中和父母双方的肤色。但第二代混血儿就不同了。如果第一代混血儿和白种人结婚，他们就很可能会生一个白种孩子；当然情况也未必一定。现在十分之一的孩子是混血人种，潜在的意思是一黑一白的双胞胎将会变得更加常见。” |
