Hey there!
I'm not much into Genetics but, I recall this discussion in one of my classes about genetically engineered agriculture...being indirectly linked to all the fat people in America.
XP
I'll look into it some more, it was a rather interesting discussion, but I was so sleepy, I slep through most of it.
xP
Something about the corn, and how Europe conducted a study feeding American corn to lab rats who in the end gained alot of weight.
Needless to say, Europe does not accept Genetically engineered corn from America.
FYI, please check out the guild rules and guildelines to how to make a good discussion topic.
What about Genetics? What kind of genetics? Refering to human genetics or agriculture? Or something else? It's so general and really you have offered nothing to discuss. Please make it a little more structured.
IF this is something that simply interestes you as a favorite type of science then this comment falls under that 'Favorite science' thread.
heart whee

...so that is why my butt is so big wink
I think genetics is really cool. My husband wanted to be a geneticist when he was in college and his dad was pushing for pediatrician, then my husband said screw it and went into the Air Force and is now in school studying Computer Science. He still talks about back in high school when he was doing his senior thesis for graduation from his high school (which was an academic magnet school) when he went to the Medical University of South Carolina and got to mutate the AIDS virus.

I've been interested in color genetics in horses. There is money in certain colors and color patterns, so the big breeders have sponsored some studies, and there is a book out from the U. of Kentucky written by Philip Sponenberg (sp). I'm sure there are other books as well. It's particularly interesting in the case of mustangs, which have no traceable ancestry by any other means. Some stallions "stamp" their get with their color pattern, while others don't. And there is a "lethal white" gene in which all the foals die within a matter of days, as their digestive tract is incomplete. These white foals are the only true "albino" horses, all others being classisfied as one of three other coat colors, including gray... all grays start as dark coated and gradually turn white with age... but their skin is always dark. Grays are particularly prone to tumors, some 80% of them having tumors by their late teens.
There is also a disease that has been traced to one stallion in the Quarter Horse breed. There is a big brouhaha about horses being registered... they must have a blood sample taken to see if they carry this gene, and if so, whether it is dominant or recessive. That particular stallion had won so much that he was bred to an enormous number of mares and there are thousands of his decendants.

Genetics has always been interesting. Potentially, it's an untapped gold mine, though figuratively speaking.
Of course, it's also a massive potential problem, considering the fact that we don't understand everything there is to know about DNA, RNA, and the like yet. Especially the human genome... and what could happen if we actually do. Genetically spliced super-humans? There's a lot of ethical issues involved with genetics, gene-splicing, and the like.
One interesting tidbit I picked up (as disturbing as it is) happens to be that in certain cases, offspring of cousins are genetically more unstable / likely to have genetic problems than those of siblings. Disturbing, no?
The odds of that? Pendant, but about 4 - 6% if I remember correctly. Maybe as bad as 6-8%.
Disgusting for some people, no? The very thought...
*Chuckles*

The types of Genetics I've always been interested in are Cancer Cells, who's chromosomes basically gets messed up and gets stuck into 'permanent reproduction'
I can't recall how many different documentaries I've seen on the subject, but one thing that interested me a lot was how Cancer tumors give off a type of chemical that makes blood vessels grow towards them. Freaky no?
I guess I'm mainly into the subject because a friend of mine had Leukemia (Not sure which kind, it was either chronic lymphocytic leukemia or chronic myelogenous leukemia) but she recovered somehow. I was told her case wasn't very serious or something...

Love genetics. The basics are pretty simple but it can also be really complicated when you start getting deep into it.
(For instance I know what DNA is, I know how it can program mRNA, which in turn can go to organelles(ribosomes I think but it has been awhile) in our cells and manufacture proteins, I understand what a massive role proteins have in our internal chemisty (or at least think I do), but I have never totally been able grasp how it can thus be responsible for our identity as a species) Any Genetics/Biology buffs out there able to enlighten me?

I worked for two years at a company sequencing DNA to diagnose potential for breast cancer in people who submitted blood samples to their doctor. What amazes me is that the president of the company I worked for (Myriad Genetics) had a patent on the breast cancer gene we were sequencing. It seems weird that a person can have a mutated gene that causes cancer and someone has a patent on it.
And, MustangDragon, that stuff about horses is fascinating.

A patent on a breast cancer gene? That sucks. Say, does anyone have a patent on diabetes yet?

I liked my undergrad Genetics course. I basically decided I hate genetics after I took it in Graduate 800 level. It's complicated and they made it complicated for us. However, I doon't hate all aspects of it. I mean I use genetics almost every day of my lab life. I insert a mutated gene into a cell or use a mutated cell line so that when I infect them with HIV they would produce the lacZ RNA which produces beta-galactosidase. Then I do my pretty assay and count the blue cells. Not that fun though... xp Quote: MyOwnBestCritic A patent on a breast cancer gene? That sucks. Say, does anyone have a patent on diabetes yet? Yup, my undergrad professor is working on those. In fact there's patents for way too many mutated genes. For diabetes type 1 there's an allele frequency involved. If you carry HLA-DR3 or HLA-DR4. Quote: Jad-Hoven (For instance I know what DNA is, I know how it can program mRNA, which in turn can go to organelles(ribosomes I think but it has been awhile) in our cells and manufacture proteins, I understand what a massive role proteins have in our internal chemisty (or at least think I do), but I have never totally been able grasp how it can thus be responsible for our identity as a species) Any Genetics/Biology buffs out there able to enlighten me? as a species. The 5%-9% species difference is in "mutations" or base changes in the coding of the DNA. That makes some of our proteins slightly different. Different genes have different alleles. My favorite think that my undergrad professor said. It's like going to Baskin Robins. You know you're getting ice cream but you have 31 flavors to choose from and if you mix and match them you get a scoop from your mom and one from your dad! That makes us genetically unique, except identical twins meaning they came from the same fertilized egg. Quote: Cherry_chain I can't recall how many different documentaries I've seen on the subject, but one thing that interested me a lot was how Cancer tumors give off a type of chemical that makes blood vessels grow towards them. Freaky no? I'm sorry to hear about your friend I hope her treatment goes well. Yup it's called angiogenesis. Tumors require blood vessels to deliver nutrients and later to get into the blood stream and induce metastasis. Therefore, tumors will secrete angiogenic factors like Basic-FGF, TGF-alpha and VEGF. Why did I screw the cancer part in my test!? MustangDragon: I think the horse breeding is really cool. I mean you do want the best stallion out there! It's somewhat similar for breeding dogs I guess.

Yeah...I'm a little new in this club, but I saw the genetics thread and had to jump in. It's not my favorite thing, but it's so fascinating that I couldn't stay away...then I read all the replies and now I feel that I'm definitely behind the loop. I only have high school level education in genetics, so...yes.
Anyway, I've always been a little obsessed with cancer (maybe in a morbid way) because of the history and such in my family. I know that it's an uncontrolled growth of useless cells, but does anyone know anything more? I mean, how is the genetic disposition for cancer determined? I'd really like to know that.
Also, who knows how hair color is determined? I was thinking, and I really don't know. I'm pretty sure it's incomplete dominance, but there was something else the teacher said that I wasn't paying attention to. Care to enlighten me?
Again, sorry if I'm posting in the wrong place or whatever. I'm sort of new here, so I'm just hoping I'm doing this right. Thanks for all your help!
