---- Sex determination: many ways to make a testis or ovary ----
One of the most profound decisions in our lives is the moment at which we
inherit either an X or Y chromosome. If the Y chromosome is present a gene
is activated that causes a testis to develop. Conversely, in the absence of
a Y chromosome the genetic program drives ovary development. Once a testis
or an ovary has formed they produce sex-specific hormones that further
reinforce our sexual fate. Understanding the genetic events that underlie
the proper formation of testes and ovaries in humans also provides insights
into what happens in patients with disorders of sexual development. By
contrast, some reptiles use the temperature at which their eggs are
incubated to determine the sex of their offspring while birds use a
completely different and little understood mechanism. This talk will explore
the variety of mechanisms that lead to that most fundamental biological
trait ­ our sex.
