★ The sex ratio is the ratio of males to females in a population. In most sexually reproducing species, the ratio tends to be 1:1.

★ This tendency is explained by Fisher's principle. For various reasons, however, many species deviate from anything like an even sex ratio, either periodically or permanently.
