and repaired before the cell division process can continue.<br />
One of the mutations that is of particular concern is a<br />
variation in the amount of genetic material in a cell. It is<br />
critical that the gamete contain only half of the chromosomes<br />
of the parent cell. Otherwise the amount of DNA<br />
would double with each new generation. This is the key<br />
feature of meiosis.<br />
Mutations that are not caught by the cell’s<br />
self‐check system can result in chromosomal<br />
abnormalities like Down’s syndrome, in<br />
which there are 3 copies of chromosome<br />
21.<br />
