True, but it would significantly increase the odds. If we assume that homosexuality is genetic, it would be a recessive gene. Let's look at the possibilities (according to what I was taught of genetics):
gay dad, gay mom = 100% gay offspring
gay dad, straight mom (w/ recessive "homosexual gene") = 50% gay offspring
gay dad, straight mom (w/o gene) = 0% gay offspring
straight dad (w/ gene), gay mom = 50% gay offspring
straight dad (w/ gene), straight mom (w/ gene) = 25% gay offspring (sound familiar?)
straight dad (w/ gene), straight mom (w/o gene) = 0% gay offspring
straight dad (w/o gene), gay mom = 0% gay offspring
straight dad (w/o gene), straight mom (w/ gene) = 0% gay offspring
straight dad (w/o gene), straight mom (w/o gene) = 0% gay offspring


Can you make me a krama tracker please? :flowers:

I think I slept through genetics.... My ex husband and I both have brown eyes and my oldest has green. How did that happen? I thought brown was dominant?

And no smartarsed jokes about another baby daddy cause trust me if I could have pinned it on ANYONE else I would have.
Brown is the dominant color. So, if you have a recessive gene for green, the brown dominates your eye color. However, your eggs can have either gene. Same with your baby's daddy and his sperm. Two greens = green eyes (25% chance in the case of brown-eyed parents w/ recessive color genes). I'm not sure how the different other colors work though. I.e. can they mix or are some more dominant than the others. That's definitely more than I was taught in grade school.

I'll stick to math.... :yay:

Not necessarily. If homosexuality is genetic (and I don't think it is) then it, in and of itself, is a recessive gene or it would be more prevalent.

If two brown-eyed people give birth to a blue-eyed child, that child still carries the gene for brown eyes and might mate with another blue-eyed person and have a brown-eyed baby. The odds go up even more if the mate has brown eyes in their family.

What I'm trying to say is that you have the same odds of giving birth to a gay child if you have two gay bio-parents as you do if you have two straight people who carry the recessive gene. And until they isolate the gene that causes homosexuality, it's a crapshoot so you might as well not worry about it.

Ok...

gay dad, gay mom = 100% gay offspring

Wouldn't that mean '100% gay of spring IF they were not gay and had off spring?

Which would mean they are not gay...because they had offspring, right?

We're discussing sperm donors, thus artificial insemination, thus two gay parents having an offspring is possible.

Not only possible but alot of gay folks are in the closet and they have "covers", etc.... wife kids, etc... say a man was gay and marries a gay woman... both trying to fit in what society has deemed as norm and has children, etc... it happens :shrug: It has no bearing on whether the child will be gay or not :shrug:

You fail genetics 101

:confused: Didn't read your own link?
"a recessive trait only becomes phenotypically apparent when two copies of a gene (two alleles) are present. In other words, the propositus is homozygous for the trait."
If two brown-eyed people give birth to a blue-eyed child, that child DOES NOT carry the gene for brown eyes. If you carry the brown eye gene, you have brown eyes! That is the definition of dominant genes. Two blue-eyed people WILL NOT have a brown-eyed child.

If you look at my post earlier, you will see percentages. Probability is highest with a gay dad (gay sperm donor).

Well, if that's the case, it pretty much disproves the homosexuality being genetic argument.

This thread is still cracking me up, even with the Human Genome Project being brought into it as well as statistics and probability... :roflmao:

Let me know in a few hundred years, when you can come up with a control group and a willing, honest lineage of out of the closet participants to test your theories... :roflmao:

...a gay man donating sperm, annonymously to a sperm bank as oppossed to just handing it over to Melissa in a jar, is just silly, kinda like me entering an ABBA dance contest or some drag queen parade.

The very desire to procreate is not gay. It can't be.
