ah, and to answer your question rather than just provide references, sexual
behaviour is entirely under hormonal control. the genetic influence is that
a gene on the y chromosome switches on briefly, i can't remember when but in
the first few weeks, causing the testes to develop, and that's it. thereon
restructuring of parts of the brain relating to activational effect of
hormones, hormonal responses and patterns, sexual behaviour, maternal
behaviour, sexual preferences.. are under hormonal control. where genes can
come into play is the quantity, proportions, sensitivity to.. foetal
hormones (ah, but we don't do genetics in psychology, so there might be more
to the story). by manipulating when a foetus comes into contact with
androgens (and there is also newer evidence for later critical periods for
organisational effects of oestrogens) you can independently sex their
genitalia, sexual preference, sexual behaviour (mounting/lordosis), adult
hormone patterns.. i worry about enquiries about homosexuality, in case
people should attempt to reduce the incidence (i like diversity).
