XY/female: proportion of XY genotypes among phenotypic females
(XY-female ratio).
XX/male: proportion of XX genotypes among phenotypic males (XX-male
ratio).
MF rate: male-to-female sex-reversal rate calculated as the number of
females among genetic males (XY).
FM rate: female-to-male sex-reversal rate calculated as the number of
males among genetic females (XX).
Sex reversal: overall proportion of individuals with mismatch between
their phenotypic and genetic sex.
