Polyploidy
Captions available
The idea
Polyploidy is a condition where an organism carries extra chromosome sets beyond its species' normal number, often from nondisjunction.
In practice
A cell dividing by nondisjunction, per Unit 6's Bio 1187, can produce a gamete with a full extra set instead of the normal single set.
Where people slip
Polyploidy adds whole sets, unlike aneuploidy, per Unit 6's Bio 1189, which adds or loses only single chromosomes.
