<p>The classification of disorders of sexual development is based on whether the karyotype is abnormal or normal and requires an assessment of sex chromosomes, the presence or absence of genes such as the sex determining region of the Y chromosome (SRY), gonadal type, and genital phenotype.</p> Signup and view all the answers

<p>Chimerism refers to an organism whose cells are derived from two or more zygotes. The most common example of chimerism in mammals is bovine freemartinism, where a genetic female is born co-twin with a male and is believed to be sterilized by testis-determining factors carried by the bloodstream via the placental anastomoses.</p> Signup and view all the answers
