The birth ratio tends towards near 1:1 though it is not 1:1, the population gender ratio can be heavily skewed by different death rates, as can reproductive patterns. i.e. did you know that genetic analyses have revealed that ancestrally, only 40% of men managed to reproduce, while 80% of women did? Maybe more relevant to what we're actually discussing.
