Reduction: the number of chromosomes is halved so that the daughter cells receive only one chromosomes from each type instead of two.
Since this is not my area of expertise, I searched Google under the key words "meiosis reduction rearrangement" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
