The Homosexuality Gene findings By Dr.Andrea Camperio Ciani

 

Paradox solved? As these two men married in California yesterday, scientists came closer to understanding why so-called gay genes persist in a population.

This is the Abstrat on the studies on the homosexuality gene by Andrea Camperio Ciani^1*, Paolo Cermelli², Giovanni Zanzotto^{3 of the University of Padova Italy.}
The studies that psycho researcher Dr. Andrea Camperio Ciani of Italy has been carrying out for many years seems to be panning out for the gay gene. Most of us that are gay know that this is not a new language that we learnt. It is something that we have always been with. Even those of us that have come out to themselves or others in the latter years of their lives can recall incidents and thoughts very early in their lives that other wise had been buried in the files of our sub-contious of denial and that if we don’t accept it, then we are not it,  syndrome. Details of his studies are beginning to trickle out. Below I posted the abstract to his gene study. On this link.plosone.org/article you can read the whole study and his calculations. The bottom line is that he believes he has narrow down his studies of homosexuality. We shall see what comes out in the following weeks about his studies and when the general media will pick it up.  Iam giving you the information has I have and Im also aware that the Huffington post has written about it today. You might want to check there and compare with what I have here. adamfoxie*

"Several lines of evidence indicate the existence of genetic factors influencing male homosexuality and bisexuality. In spite of its relatively low frequency, the stable permanence in all human populations of this apparently detrimental trait constitutes a puzzling ‘Darwinian paradox’. Furthermore, several studies have pointed out relevant asymmetries in the distribution of both male homosexuality and of female fecundity in the parental lines of homosexual vs. heterosexual males. A number of hypotheses have attempted to give an evolutionary explanation for the long-standing persistence of this trait, and for its asymmetric distribution in family lines; however a satisfactory understanding of the population genetics of male homosexuality is lacking at present. We perform a systematic mathematical analysis of the propagation and equilibrium of the putative genetic factors for male homosexuality in the population, based on the selection equation for one or two diallelic loci and Bayesian statistics for pedigree investigation. We show that only the two-locus genetic model with at least one locus on the X chromosome, and in which gene expression is sexually antagonistic (increasing female fitness but decreasing male fitness), accounts for all known empirical data. Our results help clarify the basic evolutionary dynamics of male homosexuality, establishing this as a clearly ascertained sexually antagonistic human trait.”
