Sorry I'm new to this! Anyways, here's the question:

Chromosomal mutations are changes in the normal structure or number of chromosomes.
Changes in chromosome structure can result from errors in meiosis or from exposure to radiation or other damaging agents.
Certain changes in chromosome number can result from nondisjunction during either meiosis or mitosis.
Both structural mutations and nondisjunction can play a role in trisomy 21, commonly known as Down syndrome.

The following table illustrates some structural mutations that involve one or both of these chromosomes. Identify the type of mutation that has led to each result shown.

Drag one label into the space to the right of each chromosome or pair of chromosomes. You can use a label once, more than once, or not at all.
