46
Q

Relate to an organism’s generic makeup, including the nature of the organisms genes and constituent nucleic acids

A

Genotypic characteristics

47
Q

based on features beyond the genetic level,
including both readily observable characteristics
and features that may require extensive analytic
procedures to be detected.
