Re: Will there be a gene crisis if we clone too much?

By "clone" I assume you mean clone human beings. It is always very 
dangerous to make predictions, but I don't htink that there is likely to 
be a gene crisis. 

First, human cloning is unlikely to begin for sometime because it is 
still very, very difficult to clone animals. It would be criminal to clone 
human beings at the moment.

Second, once cloning does begin, it will be available to very few 
people because it will be so expensive. This is still true for in vitro 
fertilization.

Third, even if it does become relatively common, it will still account for 
a minute fraction of  the human beings born each year by 
conventional and more enjoyable means. The impact on the human 
gene pool will be negligible. A population geneticist could probably 
do the calculation of how many births would have to be by cloning to 
alter the gene pool - my guess that it won't happen.
