Male baldness isn't solely a sex linked characteristic (X or Y chromosome), it's actually passed down via non- sex linked chromosomes (autosomes) which both parents randomly contribute. So you can inherit it from either side of your family. Also there was a recent German study (Hillmer et al, American Journal of Human Genetics, July 2005) that found a similarity in androgen receptor (AR) genes in balding men.. and while AR are found on the X chromosomes... You have to also consider that there are about 1,000 genes that are X-linked, and most are conditions that predominantly afflict cisgendered males. This is because they have XY chromosomes, in women (or those born genetically female) a recessive abnormality on one X chromosome usually is masked by a dominant normal gene on the other. I don't see how there could be a disproportionate number of transmen who go bald, such as the 38 of 40 figure that was given. Unless they were already genetically dominant for going bald or they really weren't suffering from androgenetic alopecia (pattern baldness).. but rather from hair loss due to hormonal changes. But even this should correct itself and grow back, unless it's due to an overproduction of testosterone.
