Question

Euploidy vs Aneuploidy

Answer 1

I don't know much more about this.

Answer 2

Aneuploidy. Changes in chromosome number can occur by the addition of all or part of a chromosome (aneuploidy), the loss of an entire set of chromosomes (monoploidy) or the gain of one or more complete sets of chromosomes (euploidy). Each of these conditions is a variation on the normal diploid number of chromosomes.
