英国贝奇班夫妇3年前的2月27日迎来一对双胞胎儿子,今年同一天又新添一对双胞胎女儿。专家说,一家同一天诞生两对双胞胎的几率是1700万分之一。吉尼斯世界纪录认证机构确认,这在英国是唯一一例。
British Bechtelban couples welcomed their twin sons on February 27 three years ago and added a new pair of twin daughters this same day. Experts say the odds of having two twins on the same day are one in 17 million. The Guinness World Records certification body has confirmed that this is the only case in the UK.
