Whereas recessive traits require two bad copies of a gene to become noticeable, a dominant trait expresses itself no matter what the other copy does. A benign example of dominance: If you inherit one gene for sticky wet earwax and one gene for dry earwax, the sticky earwax gene wins out every time.
A gene can be either dominant or recessive, depending on which type of gene it is.
When we talk about genes for anything, like a gene for being gay or a gene for being aggressive or something of that sort, that a gene for anything may not have been a gene for that thing under different environmental conditions.
Science is a victim of its own reductive metaphors: 'Big Bang,' 'selfish gene' and so on. Richard Dawkins' selfish gene fitted with the Thatcherite politics of the time. It should actually be the 'altruistic gene,' but he'd never have sold as many books with a title like that.
I remember the day we found the gene for the inter-species signaling molecule like it was yesterday. We got the gene, and we plugged it into a database. And we immediately saw that this gene was in an amazing number of species of bacteria. It was a huge moment of realization.
A gene might be able to assist replicas of itself that are sitting in other bodies. If so, this would appear as individual altruism but it would be brought about by gene selfishness.
Some, like Mother Teresa, are born with a gene to help the poor, and some are born with a gene to write. I was born with a gene to tell my story, and I just had to.
What does gene A do? What does gene B do? What does it do in different contexts? What's its importance? We know the answer to that for a very small number of genes, the ones that made themselves evident many years ago.
I wanted to be an actor and I wanted to be a performer. Like Hugh [Grant] said earlier, we might all have this weird gene. Hopefully I will continue to have the talent to allow that gene to play itself out for as long as it can.
What you cannot have is a gene that sacrifices itself for the benefit of other genes. What you can have is a gene that makes organisms sacrifice themselves for other organisms under the influence of selfish genes.
I hope my fans remember my name is Gene Vincent and not Gene Autry.
In the past, when we've tried gene therapy, we haven't had tools that have allowed targeted gene correction.
I still can't believe I danced with Gene Kelly. How lucky am I that I've been in movies where I've danced with two of the greatest dancers of all time - with Gene Kelly and John Travolta.
Freud had a gene for inefficiency, and I think I have a gene for efficiency.
I think it's fair to say that Donald Trump was born without the embarrassment gene or the moral reservation gene.
I knew the ribosome was going to be the focus of Nobel prizes. It stands at the crossroads of biology, between the gene and what comes out of the gene. But I had convinced myself I was not going to be a winner.
I ended up gettin a little Gibson amp and a bass, because of Gene Simmons of Kiss. Myself and three other kids would pretend to be Kiss - I liked Gene the best.
