[FRIAM] gene complex for homosexuality

[Eric Charles]

"Couldn’t this also be part of a parcel of adaptations present in mothers
to call an audible when her offspring are still in utero?"
<echarles at american.edu>

One could imagine kin-selection-ish arguments to that extent, which would
fall under Category 1. Under Certain Circumstances, it is the best strategy
to contribute to the rearing of kin rather than having your own kids, and
this is controlled to some extent by the Mother's responsiveness to said
circumstances, as present during her pregnancy.  Mother-genes that guide
advantageous responses to such circumstances are thereby passed on with
higher frequency than Mother-genes that guide neutral or disadvantageous
responses.
