Which is the correct ratio of males to females?
It’s a classic story, a tale as old as time. The sex ratio is the ratio of males to females in a population. A balanced ratio is 1:1, or an average of one male for every one female. This can also be expanded to be read in terms of hundreds, so 100:100. That’s a perfectly stable sex ratio, although the global ratio for humans is around 107:100.
What does a perfectly balanced sex ratio look like?
A perfectly balanced ratio in that form would look like this: 100:100.

That’s close enough to still be simplified as a 1:1 ratio, but many scientists are puzzled by those extra seven males.
Why are comparative studies important for sex ratios?
