Abstract in brief

  • The text discusses evidence that genetic factors influence male homosexuality and bisexuality, highlighting the evolutionary puzzle of why such traits persist despite seeming detrimental.
  • It explores the asymmetries in family lineages, particularly how male homosexuality and female reproductive success are distributed among ancestors, and examines various hypotheses for their persistence.
  • The study's key finding is that a two-locus genetic model, particularly one involving the X chromosome with sexually antagonistic effects (beneficial for females but detrimental for males), best explains the observed data and evolutionary dynamics of male homosexuality.

@FerranSuay Certainly: https://t.co/gaCM0d2Fyy Keep in mind that this is mainly the case for monogamous mammals like humans. For polygamous mammals (lions, elephant seals), there is huge, sex-based evolutionary pressure (e.g. 9 out of 10 males don't mate) increasing sexual dimorphism.

@higinih @GPursals Ciani et al. (2008) intentaven oferir una explicació als factors genètics de l'homosexualitat masculina. Aquests factors genètics podrien persistir en donar un avantatge selectiu (androfília) a les dones, cosa que compensaria l'efecte negatiu en mascles https://t.co/OkBb8jUSl6

@TJ_Knight While there is an (epi)genetic component to male homosexuality at least (Camperio Ciani https://t.co/t2NQqZt5h9), we're obligated as an ethical society to oppose creeping eugenics, AS WELL AS to demand the right to choose homosexual relations. It's not one or the other.
