A Newcastle University study involving thousands of families is helping prospective parents
work out whether they are likely to have sons or daughters.

The work by Corry Gellatly, a research scientist at the university, has shown that men inherit
a tendency to have more sons or more daughters from their parents. This means that a man
with many brothers is more likely to have sons, while a man with many sisters is more likely
to have daughters.

The research, published online today by the journal Evolutionary Biology, involved a study of
927 family trees containing information on 556,387 people from North America and Europe
going back to 1600.

"The family tree study showed that whether you’re likely to have a boy or a girl is inherited. We now know that men are more likely to have sons if they have more brothers but are more likely to have daughters if they have more sisters. However, in women, you just can’t predict it," Mr Gellatly explains.
