The number of elements ( copies ) in a gene family ranges from two to more than
10° ; the human genome , for example , contains the Alu family of more than 500 ,
000 copies , among which there is only minor variation in nucleotide sequence ...

There is little evidence that small differences in the number of copies in a gene
family have a substantial effect on fitness simply because of total DNA content .
Rather , amplification of the number of copies is likely to affect fitness because of
...

For example , about 400 copies of a sequence carrying the 18S rRNA and 28S
rRNA genes and a nontranscribed spacer ( NTS ) are distributed over five
chromosomes in the human genome ( Figure 1 ) . Each of these units has a
recognition ...
