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.

Estudios sobre la homosexualidad hay demasiados. Y estudios serios y bien documentados.

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

@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.

This study used data from all adult twins in Sweden to examine the roles of genetics and environment in same-sex sexual behavior, making it the largest study of its kind so far. The results showed that genetic factors…

@MissDTiare @WaMaruhh @alfakeky2 Te dejo estos dos como para que arranques, googleando los encontras:

De nada.
