heteromorphic

Matthews and colleagues’ genome will provide researchers with the opportunity to examine how the homomorphic sex chromosomes of A. aegypti are maintained, rather than evolving into heteromorphic chromosomes that are broadly different between the sexes — a better-understood phenomenon that is exemplified by the human X and Y chromosomes.

Organic development is not like crystallisation; it is heteromorphic crystallisation, so to speak.

It is open to question, however, how far the evidence from such “heteromorphic regeneration” can be regarded as conclusive on the points of homology.

Heteromorphic, het-e-ro-mor′fik, adj. deviating in form from a given type—also Heteromor′phous.—ns.

The occurrence of heteromorphic unions renders it necessary to keep in mind that plants hermaphrodite as to structure are by no means necessarily so as to function.
