flag Study reveals two non-inherited genetic factors influencing human 1:1 sex ratio through X and Y chromosome distribution.

flag A study by University of Michigan researchers Siliang Song and Jianzhi Zhang investigates the human 1:1 sex ratio, identifying two genetic variants affecting it, which are not inherited. flag Unlike many animals with skewed ratios, humans maintain this balance through X and Y chromosome distribution in sperm and eggs. flag The findings suggest that evolutionary and statistical mechanisms, along with human monogamy, contribute to this equilibrium, despite high genetic variability.
