Biological Abnormalities Chromosomal Abnormalities Hormonal Abnormalities Gender Identity Creation/Change

KEY CONCEPTS Chromosomal Abnormalities Hormonal Abnormalities Errors in cell division lead to extra or missing chromosomes Turner’s Syndrome (X Ø) Trisomy X Syndrome (XXX) Klinefelter’s Syndrome (XXY or even XXXY) Supernumerary Y Syndrome (XYY) Hormonal Abnormalities It’s the ratio of androgens/estrogens that make us male/female Androgenital Syndrome (too much androgen) Androgen Insensitivity Syndrome (normal androgen, body can’t use it) Gender Identity and Gender Of Rearing The “Creation” Of Gender Identities When Gender “Creation” Doesn’t Stick

X Chromosome Y Chromosome

XX - Female XY - Male

In the absence of a “Y” chromosome, these are females. Turner’s Syndrome Trisomy X Syndrome In the absence of a “Y” chromosome, these are females.

Klinefelter’s Syndrome Supernumerary Y Syndrome In the presence of a “Y” chromosome, these are males. They are “Pseudo-hermaphrodites”
