Answer:
By a definition numerical, affecting whole chromosomes (see POLYPLOID and ANEUPLOIDY), and
structural, affecting genetic arrangement within chromosomes. These are usually of a fairly major type (compare POINT MUTATION) and often cause severely adverse effects. Such structural mutations are classified into various

Explanation:
new cells rather than growing bigger. Why is this ?
There are two main reasons why cells divide rather than continuing to grow larger and larger: ... If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Cell Division. Cell division is the process by which cellular material is divided between two new daughter cells.
Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions?
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? again The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
