Describe Nondisjunction and provide a diagram to show how it happens

Mr. Bonnah will decide

What organisms experience polyploidy, what are some advantages of this?

Plants, more versions of an allele equals more diversity, allows them to choose the "good" versions of the genes over bad ones they might have.
