What's you're talking about there are recessive genes, for example the genes for ginger hair or having no earlobes. If one parent is a carrier of the recessive gene but the other has the dominant genotype, the dominant phenotype will be displayed. However, unless the characteristic bought about by the recessive genotype actually prevents the animal/person from reproducing, the genes will remain within the gene pool. I.E. ginger people do reproduce... Homosexuals rarely reproduce and so if it was genetic, the trait should have been eliminated long ago. However, there are many social factors involved. Not too long ago, homosexuality was considered a disease or perverted so many would-be homosexuals may have lived in straight relationships and in fact reproduced. It also may be caused by random mutations within certain genes....
I really suggest you take a basic genetics class.
>>>"Homosexuals rarely reproduce and so if it was genetic, the trait should have been eliminated long ago. "
This statement is completely false. Completely.
[False] Assumptions you made:
#1 - Homosexuality is controlled by a single gene. In fact, almost all mammalian traits are coded by a lot more than 1 gene. Even eye color, buddy. If there was a single gene, I guarantee you it would have been found by now. Because it is NOT a single gene, your dominant/recessive claims are irrelevent.
#2 - Genes have independent assortment. FALSE! Genes are linked to each other because of their proximity on the chromosome. So, IF there really was a single homo gene, it wouldn't necessarily die out of the gene pool because other genes would drag it along. Let emphasize that in all likelihood, it is NOT a single gene.
#3 - Random mutations can consistently cause a single phenotype. Do you know what the chances are that homosexuality is caused by random mutations??? Close to zero!
Because of these completely false assumptions, you really have no argument that homosexuality is a completely social happening.
In all likelihood, a large combination of genes give a predisposition to homosexuality, and environment takes it from there. But there is not a single ounce of proof of what environment and what degree of predisposition is required to "Create" a homosexual.
If it was as simple as drop a kid in a homosexual family and he becomes gay, I am 100% positive that it would have been in a scientific journal by now.
Unnatural enviornment is your personal opinion. There are others who disagree with you.
It is an unnatural environment. A natural environment is one where the genetic parents raise their offspring. This is what you can observe throughout nature and is the only way in which new generations can be produced. Same-sex couples are not natural. This is not to say it is wrong, or whatever, but strictly speaking, it is not natural.
That's an interesting definition of "natural". My dictionary says: "Faithfully representing nature or life." Homosexuality is found throughout nature.
By your definition of "natural", a sexually dysfunctional male married to a healthy woman would not be a natural enviroment for a kid. Are you against all forms of adoption?
Really, you should use a better word than natural. Be straight with us. How about "morally correct"? Cause that's what you really mean.
