Genes Definition and 112 Threads

Way back in the dark ages when I went to high school, we where taught that humans had 32(?) chromosomes and that each chromosome contained individual genes which was what actually passed on characteristics and traits like eye color etc. So now there is DNA and the humane genome is billions of...

Once a trait is established to its environment, might that indicate, by definition or process, that it is more likely resistant to further changes in that environment?

There seems to be a lot of confusion about the influence of genes on phenotypes. I happen to have worked in the field, so I will just give my view on the matter. Geneticists are studying populations and try to find genes that cause the population to be at risk for certain phenotypes. Examples...

Genes may to blame for infidelity (quote) Some people may be genetically programmed to be unfaithful to their partner, a scientist has claimed. Professor Tim Spector, of the Twin Research Unit at St Thomas's Hospital, London, says he has evidence of a genetic component to infidelity...

I used to read a thread created quite long ago about human gender genes and I tried to do a search for it again but found nothing... I have a question as to why some people turn out to be biosexual, gays or lesbians...Is that a problem due to surrounding environment or a problem caused by sort...

hay all, what are your views on 'god vs genes'? its just the more we follow science the more we move away from god. the reason I am asking is because i want to know if there are still physicists out there who still believe in god. i think that there never was a god in...

PRESS RELEASE UCLA Team Maps How Genes Affect Brain Structure, Intelligence UCLA brain mapping researchers have created the first images to show how an individual's genes influence their brain structure and intelligence. Complete text at...

this is an exerpt from this article: http://www.mdausa.org/publications/Quest/q92resup.cfm#mdasgenetherapy "Meanwhile, MDA is also laying the groundwork for a clinical trial of AAV-based gene therapy for Duchenne muscular dystrophy (DMD). DMD results from any of a number of mutations in a...

Hey guys, So I have an exam tomorrow afternoon on developmental bio (ugh ), and i have been going over my notes and have run into something I'm struggling to understand. The topic is Drosophila development, and the brick wall I have run into involves the way in which pair-rule genes work...

Gene patenting is set to become one of the major issues of the new century with corporations rushing to cash in on the pioneering research of the Human Genome Project. It is now possible to isolate our genes and identify them. Ultimately, this new knowledge is expected to lead to tangible...

My wife and I are animal lovers. We don't watch the pet psychic and we don't have funerals for our pets. I do enjoy analyzing out pets' [cats and dogs] behaviors and something really interesting occurred to me. My pets tell willful lies! Both cats and dogs clearly understand that they are not...

I just want to ask a few questions on genes n hear some of your views... 1)if identical twins have the same genes then how come identitcal twins still exhibit phenotype differences?( like one have a mole and the othe not having one)is it because of alles? 2)Why is it that species cannot mate...
