I think you need to re-read post# 1605. I was not talking about genes that are functioning, I was speaking of just duplicated genes which are adding no new functionality to the organism and the process up until the time when they supposedly do develop a new function in an evolutionary way. So your statement above is not relevant.
BTW - is that what the female sea-lions told you? They told me otherwise, but it is not fit for publication in a family forum. :)
Like I said earlier, sometimes the duplicates are expressed and lead to an increased level of the gene product. This could conceiveably have a benefical effect. Even if it is silent for the time being, it will be carried due to its proximity to the parental gene. Eventually it might find a function.

I think that was a female bonobo chimp. Read about them if you want really want a shock.
