Here are some questions that came to mind as I drove to work today, brought on by hearing on the radio about a new gay-themed movie called “Brother to Brother.” I present them in the same order I thought of them.
1. Given that the primary function of the incest taboo is to prevent mating between people who are too similar genetically, should adult gay incest be considered okay?
2. Assume the answer to the question above is “yes.” Would the answer change if new genetic engineering techniques allowed members of the same sex to have a biological child?
3. Bonus question. If the hypothetical genetic engineering technique worked only through the combination of whole chromosomes contributed by the same-sex parents, what sex possibilities would be available for the offspring?
I will post my answers in the comments section.
