1.Karyotypes are just the stained chromosomes from the nucleus of a cell. Only large abnormalities are picked up, such as differences in chromosome number. They are not supposed to be like DNA which would be similar to the parents.

2. -calculate the chance of affected people of the people
-karyotyping of that family will help u diagonse the probability of the diseased members

Hope that helps ps: check the sites Ms.Sue has gave you :)
