"Female Gouldian finches 'decide' to have more male chicks if they are less compatible with their mate.

The birds, which have either red or black heads, prefer to mate with males with the same head colouring, as this signifies a better genetic match.

Chicks from a mismatched mating - particularly the females - are weaker and more likely to die very early.

A report in the journal Science says that the birds compensate for this by having more male chicks in their brood.

Join the ongoing discussion about whether or not humans should use technology to select the sex of offspring when a genetic roll of the dice is a risky proposition.

At least one clinic in the US is using preimplantation genetic testing (PGD) and in vitro fertilization (IVF) to allow parents to select traits such as the hair and eye color of their children. The clinic director expects a trait-selected baby to be born next year. (This technique has been used for years to help select embryos free sex-linked and other genetic diseases, but the deliberate selection of non-medical traits is new.)

A new paper published in the Procedings of the National Academy of Sciences suggests that, as parents preferentially select boys over girls and gender imbalances grow, we'll see rising levels of anti-social and violent behavior.

"There are already an estimated 80 million missing females in India and China alone."

(According to the World Bank, in 2004 48.6% of China's population and 48.7% of India's population were female. By contrast, females made up 49.1% of the total population in East Asia, and 52.1% in all of Europe and Central Asia.)

The Reuters news report says,

"'This trend would lead to increased levels of anti-social behavior and violence, as gender is a well-established correlate of crime, and especially violent crime,' [the authors] said, adding the trend would threaten stability and security in many societies."

The authors of the paper call for "measures to reduce sex-selection and an urgent change in cultural attitudes." But that seems easier said than done.

Do you think it's possible to change cultural attitudes about gender preference? It's easy to say this is a problem of East Asian cultures, but what about the US? Do we have cultural preferences about our children's genders, too?
