Considering how many mothers in the DWU are not specified as biological, this category is open to some of the worst kind of speculation.
Per T:GENDER, no categories whose topics are not directly related to gender may use gendered language. Thus, 'adoptive mothers' should never exist, as gender has no bearing on adoption. This particular category is allowed by T:GENDER because sex has a direct link to sexual reproduction, and biological motherhood is a characteristic, dependant on sex, of sexual reproduction.
If you are unsure whether or not an individual is a biological mother (by means of sexual reproduction), please do not place them here.
