Upon arriving on Pluto, you discover a new race of aliens. You observe that
Plutonions range from having no orange spots at all to being almost completely
covered in orange spots, with a whole spectrum of orange-spottedness in between.

trait?

Polygenic inheritance occurs when there are more than two alleles possible for a
given locus.
a. True
b. False
4.
