　 76 But science may have just proved them right - because beautiful women are more likely(可能的) to have daughters than those who are ordinary-looking, according to a study.

As parents often pass on genes(基因) that determine(决定) looks, this could result in fewer handsome

men on the ground. 77 For example, Yasmin Le Bon is signed to the same modelling company as daughter Amber, and Jerry Hall's daughters Elizabeth and Georgia Jagger have both taken to the catwalk.

Dr Satoshi Kanazawa, of the London School of Economics, surveyed( 调查 ) 17,000 babies born in

Britain in March 1967 and followed them throughout their lives. 78 When they reached 45, they were asked about the gender(性别) of any children they had.

Those considered to be attractive have the same chance to have a son or daughter as their first child -

but the unattractive ones were more likely to have a son. 79

　　A previous study of 2,000 Americans suggested that women are becoming more beautiful over the generations because attractive women have more children than unattractive ones - and a higher percentage of their children are girls.

Dr Kanazawa believes that parents are more likely to produce children who benefit( 得益) from their

own features. 80 So it pays for attractive women to have daughters. But couples with strength and aggression rather than looks are better off having boys, as these characteristics are of more use to males.

A. Famously good-looking parents like Tom Cruise and Katie Holmes are more likely to have girls than uglier couples.

B. Single girls have always complained that good-looking men are difficult to find.
