I personally do not believe there is a homosexuality gene but the author’s science is flawed.
The home gene may require that the gene be carried on both the mother and the father’s genes for it to be expressed. This would mean that a man carrying the gene but not expressing the gene (not being homosexual) could pass it on to his offspring
Also there are many genes that we all carry that are not expressed unless some outside stimulus activates the gene. One theory on homosexuality is that the amount of male hormone in the mother’s blood at a specific point in the pregnancy alters the fetal brain in such as to cause homosexuality.
Regardless of what is the causation of homosexuality the science of the article is flawed.
If we are bound and determined to debate genetics, yet another analogy is that of the sickle cell. It confers resistance to malaria.
Sin has roots in events that are pre-conception. We should be very careful. There are genes for susceptibility to alcohol abuse. We do not tell such people that it is just fine to get soused.
Sorry about the remnant of a previous post there.
Again, the low correlation of homosexual attraction among identical twins does not support your argument. It has yet to exceed 11 percent, which makes it statistically insignificant.
if what you argue were true, then in every set of identical twins, where one twin expresses same sex attraction, then the other must also express the same attraction to the same degree. Since this is not the case, then your argument cannot be valid.
