Researchers find that certain genetic variants and mother’s age may have an impact on the sex of her children



Summary

A new study suggests that genetics and maternal age can influence a woman’s likelihood of having sons or daughters. Researchers identified specific genetic variants associated with a tendency to give birth to more sons or daughters. Furthermore, the study found that older mothers were statistically more likely to give birth to daughters. These findings provide insights into the complex biological factors that determine the sex ratio of offspring, potentially challenging existing understandings and prompting further investigation into the mechanisms at play.
