Add a definition Some studies on heterophylly have proposed possible mechanisms to explain the ontogeny ofheteromorphicseeds. From theCambridge English Corpus Most heterostylous species possess aheteromorphicincompatibility system in which intra-morph (assortative) mating is prevented physiologically. From theCambridge English Corpus Leavesheteromorphic, usually with dentate or digitate margin. From theCambridge English Corpus However, it is important to recognize that this analysis assumes that post-pollination mechanisms play no significant role in influencing siring success, as they would in a species withheteromorphicincompatibility. From theCambridge English Corpus Gabbro shows ambiguous, possibly liquid-liquid, contacts with porphyritic diorite, which resembles an altered orheteromorphicversion of the gabbro. From theCambridge English Corpus They also have aheteromorphicpair of central microtubules in the anterior axoneme. From Wikipedia ![]() The haploid prothallus does not resemble the sporophyte, and as such ferns and their allies have aheteromorphicalternation of generations. From Wikipedia ![]() The thin shelledheteromorphicammonites probably lived at depths 36-183 m. From Wikipedia ![]() Plants withheteromorphicleaves generally have pinnately divided basal leaves with either filiform (feather-like) or linear segments, and undivided leaves higher on the stem. From Wikipedia ![]() Land plants all haveheteromorphic(anisomorphic) alternation of generations, in which the sporophyte and gametophyte are distinctly different. From Wikipedia ![]() Seed producing plants, which include the angiosperms and the gymnosperms, haveheteromorphicalternation of generations with large sporophytes containing much reduced gametophytes. From Wikipedia ![]() In this species, there is a physical dimorphism: one type is cryptic (heteromorphic) and the other type looks like a male (andromorph). From Wikipedia ![]() The initial part (juvenile stage) of the shell is generally more or less involute (tightly-coiled) and compressed, giving no hint of theheteromorphicshell form yet to come. From Wikipedia ![]() Some early plants may have hadheteromorphicalternation of generations, with later acquisition of isomorphic gametophytes in certain lineages. From Wikipedia ![]() The two style morphs are genetically determined, so the pollen from one morph does not fertilize the other morph, resulting in a form ofheteromorphicself-incompatibility. From Wikipedia ![]() Heteromorphicflowers have short carpels and long stamens, or vice versa, so animal pollinators can not easily transfer pollen to the pistil (receptive part of the carpel). From Wikipedia ![]() These examples are from corpora and from sources on the web.
