Using Close Genes: A Suggestion
Today, if a gay couple wants to have a child, they have two main options: Either (1) they adopt a child or (2) they get an egg from a donor, have it fertilized in a laboratory, and have a surrogate mother carry and give birth to their child.
These are both good options. Imagine, however, that a certain gay couple – let us call them Albert and Mark – wants a child that genetically belongs to both of them. If they want this, then option (1) will not do the trick. Option (2) will be somewhat better, but the child will then carry genetic material from only one of the two.
This does not satisfy Albert and Mark.
Is their problem solvable? Can Albert and Mark have a child that, genetically, is truly theirs? The answer that first strikes one is no, since this seemingly requires technology beyond reach.
It is easily solvable, however, if we just think outside the box. The solution is that the egg fertilized by Albert’s sperm should come from Mark’s sister, or if still fertile, form Mark’s mother. This would not give a perfect genetic match, but a decent one – and it would be safe, affordable, and fully possible. Even legal, I assume, since it does not imply inbreeding.
Why should not gay couples do this? Or, for that matter: Why should not straight couples where one party is infertile?
