I guarantee you all of your mothers and grandmothers have seen penises before. Some more than others, of course.
Very true.
My mom still wouldn't like it, though. She's gotten a lot more conservative since her wedding, which I attended in utero. And the bride is still settling on the guest list, but as of now I think the junior bridesmaid and flower girl are on it, so tame games it is.
Very true.
Hey, it's true! Wedding: Feb. 9. IPB born: July 1. In all the wedding photos, she's holding her bouquet in front of her stomach.

Well, I thought "in utero" sounded better than "as a fetus".

At first I read this as "My sister has a penis"
Very true.
No milk!!! That's awful.
My twin sister temporally displaced.
Agreed. Lactose intolerance... fat.... not to mention those insane people who drink raw milk. Um, excuse me, we invented pasteurization for a reason!Milk is bad for your health......
Not very lady like lol
I'm realizing that I swear like a sailor.
my mom gives me so much ****e about it.... she says I need to stop ... I tell her to come here and make me
It is a ploy to make her come visit... but I will not stop.... it is part of the culture here - must do it to fit in!
After being a trader for so many years, I didn't realize how acceptable swearing had become until I spent time around my family. They wereI'm realizing that I swear like a sailor.
at my language. I was like, what's the f*cking big deal?

People have been drinking milk for hundreds of years. It's fine. lol It's fine if you don't drink it either.

Well yeah, but that doesn't mean a whole lot as far as the nutritional quality of milk for post-weaning animals - it's just very metabolically demanding for a female to lactate so once the offspring don't actually need the milk for sustenance anymore and can digest and utilize food properly, it wouldn't be advantageous for the animals or for the species as a whole for the females to continue to lactate past that.
But the RESULT, which I think is where your question is leading, is that yes, the ability to break down lactose is indeed a fairly recent mutation in humans and that means all of you who are lactose tolerant are genetic freaks.

), it doesn't make any difference whether they do or don't (try to ) consume milk, without supplementing with lactase they won't be able to break down lactose because the gene is permanently downregulated. But in a person who doesn't drink milk regularly despite possessing the mutation that allows for lactase production later in life, it's quite possible that lactase production could decrease due to the body not needing it. The difference is that this would be more likely to be transient, and starting to drink milk again would be painful at first due to the previous loss of gene expression, but the gene could be upregulated again if lactose continues to be present. Same goes for bacteria - in fact the lac operon in prokaryotes is very widely used in intro bio and genetics courses as a very clear example of regulation of gene expression.
I'm sure it could be a factor, but the ability to produce lactase is present in all of us from birth, just that the regulatory factors determine whether it's produced at any given time. So in a person who is lactose intolerant due to "genetic" factors (aka us normal people
Does that make sense? Sometimes it's hard for me to discuss genetic and epigenetic things with people without forgetting that not everyone has the same interest and background that I do in genetics.

....I love it when you talk genetics.
I did get an interview!I don't get to do it nearly enough in vet school.
If I read correctly in another thread you got an interview at SGU? GOOD LUCK!! you'll own it.
