Furthermore, research has been done in order to locate the possible gay gene. In “A linkage between DNA markers on the X chromosome and male sexual orientation” geneticist, specifically Hamer, investigated family …show more content…
If this family of 10 boys were to roam around looking for a mate to reproduce with then the likelihood of one of the boys having interest in the same girl is higher which would result in sibling rivalry. In extreme cases sibling rivalry could lead to death, penitentiary, or them both single. In all these scenarios the chance of that family genes being passed on is diminished. However, if in the same scenario instead 1 out of the 10 boys are homosexual then the possibility of the family gene would be increased. The family gene would be increased because that’s one less boy competing for a partner to reproduce with and that gives the other 9 a higher chance of not being involved in sibling rivalry. Even though the final boy may not be a part of the reproducing population that boy increases the odds of reproduction, overall increase that families fitness. As you can see, the “gay gene” is possible in terms of evolution because it doesn’t cause a negative effect to society’s fitness but actually the opposite by increasing our
