Brenda Barnes16 said:Basically, people with blue eyes on both chromosomes (15 and 19) who carry that specific eye color gene only pass down that one gene (meaning they can only pass on blue eyes). But since people with brown eyes often carry hidden genes for blue or green, that’s why you see brown-eyed parents having kids with blue eyes.
Sorry, but that whole thing about two loci determining iris color comes from a study published like 30 years ago 😉 (Brues et al., 1975) In this article from 2003, they actually looked at 6 different genes involved in iris pigmentation, and they even mention 5 more regions.
On this site, you can find a simplified diagram for predicting eye color using those 6 genes.
John Richardson4 said:Yeah, and it’s not like some random crew just shows up to grab the umbilical cord stem cells. For this lady, the midwife did the whole thing herself, then handed the blood off to a courier who drove it straight to Denver at room temperature. They’ve got a 48-hour window after birth to get everything processed and frozen.
You've got a point. I was actually just reading about how they basically send you a DIY kit to your house these days. So I guess the main issue is really just how it gets stored.
Out there—like in Austria or Germany—it’s not actually doctors doing this, it's private companies. They have to have some kind of contract with both the mother and the hospital so they can show up on short notice, grab the stem cells from the umbilical cord, and get them straight into liquid nitrogen. Obviously, the whole thing costs money, and storing the cells later isn't cheap either. Plus, you can't just do this at any random hospital.
Doctors, regardless of whether they're here in the States or abroad, will collect those cells if the mom gives the okay, usually for research or stem cell studies, but not for private storage. Which makes sense, I guess, for the reasons I mentioned. Maybe we'll eventually see more companies popping up here offering cord blood storage services too.
I don't know the specifics of that one case someone brought up, but honestly, if I were the OB on duty, I wouldn't want some random crew hanging around my delivery room either. Since we don't really have clear legal regulations for this yet, how am I supposed to know—or even trust—that these people actually have the permits, the training, or the skill to pull this off? If something goes sideways, like an infection, who takes the fall? It's the doctor on call, every time. And yeah, it might not even be the most considerate thing toward the other moms in the room, especially in places where you can't easily isolate patients. At the end of the day, the crew coming in to do this isn't even part of the medical team.
Carol Jackson45 said:Not happening. That's just basic genetics and logic.
Yeah, I can. Your "model" kind of assumes that simplified Mendeleev genetics apply everywhere, which isn't really true. It also assumes the pattern is totally uniform across the whole surface, which... yeah, also isn't right.
Then go ahead and explain to the admin (or me, honestly) where it says that, and why you think the Kokosinjac subforum is some kind of den of evil. Please let me use that as a sig later.
Back to the point: if you’re really trying to force this angle, I guess you're just missing the mark again. The question is literally about how marijuana affects the development (development!, development!) of the fruit, not any potential issues with the embryo.
The question is about how the fruit actually "develops." So, I guess we're talking about what happens after conception. Assuming the mother is carrying the baby, the father smoking marijuana probably only plays a peripheral role.
Man, if you can't quit smoking weed while you're pregnant, just forget it. Normal people just give it up, no need for some huge debate on a forum. The world doesn't need another kid born struggling, maybe even with some issues they didn't ask for, because their parents couldn't even ditch one bad habit for a year. Getting a kid on their feet later is way harder.
I see those "floaters" too, though they kinda remind me more of staph infections to be honest. Back when I tried to self-diagnose that, I rushed to my eye doctor, and after checking everything out, he told me it was probably just vitreous changes—which I guess is pretty common if you're nearsighted.
It's the same thing when I look at a bright background; they aren't still, they just float around. Like, if I look up, they "jump" and then just slowly drift downward or whatever.
