Umm, shit for brains? How the fuck do you think you can establish there is a possibility and gloss over the entire biological process AT THE SAME FUCKING TIME???
Because of how sperm works, like at the basic middle school sex ed level.
Is your theory that some sperm, depending on their content (in terms of genes) affect its ability to reach and fertilize an egg?
Or that hormone levels affect the genes found in sperm produced?
Either of these would be a reasonable hypothesis that could be tested. But the implications depend on the underlying biological process, so that cannot just be “glossed over”.
Nope,
Yes, I suspect that neuro chemicals affect the sperms behavior enough to influence which sperm fertilize the egg.
Only glossing over it at the early stages of a discussion, I would become purely a spectator beyond that point.
I have modified my position here somewhat since I posted that. The hormones seem to play a part in selection in a few areas. including the actual fertilization process.
The mechanism by which sperm passes on traits is through the genes present in the sperm.
Sperm is a gamete so it only has one of each pair of genes.
Hormones and chemicals cannot change the genes which a sperm carries. They could break some of the genes by causing damage to the sperm’s DNA, which would cause birth defects or an inviable embryo, but I don’t think that’s what you were asking.
If the chemicals disproportionately damaged sperm carrying one set of genes, or if as I said earlier different sperm performed differently at the task of reaching the egg with the difference correlating to carried genes, then perhaps what you propose could be possible. But again, we cannot gloss over the mechanism because that determines what actual effects are possible.
Sure ya have!
Ok.
It’s outlandish because the traits (like blue vs brown eyes) we pass on are small clumps of DNA. With the possible exception of gender (as it involves an entire chromosome) no individual trait has the ability to change the behavior of a sperm cell, and our hormones do not impact which traits are present within individual sperm cells.
It’s also outlandish because “the selection process” doesn’t happen at the sperm/egg level, there is no selection process that picks out an individual sperm cell for the task, it’s basically random, or at least it’s not controlled by an outside factor. The closest thing to a selection process is that you may have fertilization happen when the sperm present are more likely to have X chromosomes than Y chromosomes, or vice versa.
I was going to bring up gender but apparently Recent studies find no evidence for even gender having an impact.
I think you’re proving why that isn’t true.
No, he’s correct. Advanced biochemistry isn’t required, only middle school health class level understanding.
I’m reasonably certain that you’re feeding the troll here folks. He’s loving it, which is why he keeps showing up to stir.
Not that most of us can stop the tendency, just a reminder.
You’re sooo generous!
Cool! Thanks for that.
I have been lurking in this thread but not responding. So I ask the question, and this will be the only time I participate, WHY do you respond to the “guest of honor” and give them the attention they seem so desperate for?
The pearl divers of Ama Japan would be an interesting thing to look at on this topic. Could they really have evolved in the amount of time given on just pure genetics?
Primary engagement is to ask questions that show the “guest(s) of honor” are not actually interested in an honest discussion.
Secondary engagement is to give them the attention they desire since they seemingly always want even more attention than they’re getting. Force feeding them puts them on ‘tilt’ and the ban hammer falls shortly after.
I present Exibit A your honor,
Thanks, I didn’t realize just how infantile and disconnected from reality the OP’s posts were.
On the other hand, the rest of us sometimes have an interesting conversation as a result.
