Which is a Limitation of Using Only Morphology to Recognize

Question

Which is a limitation of using only morphology to recognize species?
A) This approach requires detailed knowledge of genetics and mating behavior.
B) Morphological variation rarely reflects reproductive isolation.
C) Genetically identical clones are always morphologically identical.
D) Morphology cannot be used in field guides.
E) This approach will not distinguish cryptic species.

Accepted Answer

Morphological traits may not differ significantly between closely related species that look very similar to each other, i.e., cryptic species. Hence, relying solely on morphology may not be sufficient to identify such species.
