Beyond X-X and X-Y 289<br />

ample room for playing or jamming <strong>the</strong> score differently in different<br />

contexts.<br />

The fact that a cell does not use all <strong>the</strong> genes in its genomes at once<br />

problematizes <strong>the</strong> concept of genetic sex as a static and fi xed object.<br />

An example of this is those X-X individuals who have <strong>the</strong> SRY (which is<br />

typically found on <strong>the</strong> Y chromosome) on one of <strong>the</strong>ir X chromosomes.<br />

Because <strong>the</strong> genes required for <strong>the</strong> typical male phenotype are not on<br />

<strong>the</strong> Y chromosome, this gene is able to activate typical male genetic<br />

processes in X-X cells and leads to a male phenotype. A notion of genetic<br />

sex related to <strong>the</strong> genetic process would appreciate <strong>the</strong> situation in terms<br />

of <strong>the</strong> person being a genetic male because <strong>the</strong>ir genetic processes<br />

are that of a typical male although his karyotype is nontypical male.<br />

Clearly, <strong>the</strong> concept of genetic sex is tightly linked within both society<br />

and science to <strong>the</strong> karyotype, and is thus extremely resistant to change.<br />

However, devising a concept of a living genomic sex, where <strong>the</strong> stress is<br />

placed on <strong>the</strong> genetic processes of <strong>the</strong> body, might be useful.<br />

Moving toward a concept of living genetic sex follows Fausto-Sterling’s<br />

(2000) call to recognize that nature and nurture cannot be separated.<br />

Within genomics, genetic processes cannot be separated from <strong>the</strong> cellular<br />

environment in which <strong>the</strong>y occur, nor can <strong>the</strong>y be separated from <strong>the</strong><br />

local (tissue) and global (body) biological environment that <strong>the</strong>y occur.<br />

One example that brings to light <strong>the</strong> typically hidden genetic processes<br />

that take place during puberty is 5 alpha-reductase defi ciency. This<br />

syndrome is caused by <strong>the</strong> body being unable to produce <strong>the</strong> enzyme<br />

5 alpha-reductase, which is needed to process testosterone into its<br />

stronger from, dihydrotestosterone. Numerous genes lead to <strong>the</strong> person<br />

being born with an X-Y karyotype and ambiguous female genitalia.<br />

Two genes have been shown to be implemented in <strong>the</strong> defi ciency, with<br />

more than 20 mutations having been characterized, again stressing <strong>the</strong><br />

inadequacy of focusing on <strong>the</strong> DNA sequence. Once <strong>the</strong> person reaches<br />

sexual maturity she is likely to begin developing male characteristics as<br />

<strong>the</strong>ir testis descend and <strong>the</strong>ir voice drops. Historically, scientists viewed<br />

<strong>the</strong>se individuals as genetically male, even in childhood. Because this<br />

condition may only be recognized when <strong>the</strong> child fails to menstruate,<br />

this can cause a confl ict between her self-identity and what science seems<br />

to say has been <strong>the</strong>ir “true” genetic sex. I argue that a view of genetic sex<br />

should be rooted in <strong>the</strong> body’s genetic processes, as opposed to being a<br />

characteristic dictated by <strong>the</strong> X and Y chromosomes. This would allow<br />

us to understand how <strong>the</strong> body responds and develops as novel genetic<br />

processes are set in motion, as well as <strong>the</strong> infl uence of hormones on<br />

existing genetic processes. This last infl uence is especially relevant in <strong>the</strong>
