The family tree study showed that whether you´re likely to have a boy or a girl is inherited, "says Gellatly."
他说:“谱系研究显示,你生小孩是男是女的可能性有多大,这是遗传的。”
After sorting through 927 family trees from North America and Europe, including 556,387 people in all, Gellatly proposes another explanation.
盖里特利在对北美洲和欧洲927个族谱的556387人进行研究后做出了另一种解释。
Gellatly hypothesizes that the gender-controlling gene comes in a "male" and "female" version , with three possible combinations of the two.
盖里特利假定,性别控制基因由“m”和“f”组成,它们有三种组合方式。
"The structure of the proposed gene is essentially very basic, and its function is simply to say ´produce more boys´ or ´produce more girls, ´" Gellatly explains.
盖里特利解释说:“这种基因的结构从本质上来说很简单,它的功能也很好解释,那就是‘更容易生男还是女’。”
Gellatly was curious about studies of male shrimps, Marine worms, and yes-human males-that showed that their likelihood of producing male offspring seemed to mimic that of their parents.
加拉·特里对雄虾、海生蠕虫——当然还有男性——的研究很感兴趣,这些研究显示,他们生产后代似乎是在模仿自己的父母。
