Sentence examples for morphological characters but from inspiring English sources

The two species cannot be reliably distinguished using morphological characters, but are readily identified and distinguished by simple, rapid, and inexpensive molecular protocols based on sequence variation of mitochondrial DNA (mtDNA).

Relationships at the generic and deeper levels were broadly consistent with those proposed by Harbach20 based on morphological characters, but greatly expanded upon that author's taxon sample (28 genera within two subfamilies).

This indicates that, species discrimination seems possible with morphological characters, but reproductive isolation appears to be weak in Berberis and in many cases probably only affected by geographical barriers.

For example, Hippopotamus amphibius was coded for morphological characters, but for many genes that we sampled, molecular data have not been generated for this hippopotamid species.

The two species share many morphological characters, but the genome of S. macrophylla is ∼25%% larger than that of S. speciosa (Zaitlin and Pierce 2010).

Limits of species with distance to nearest neighbour < 2% in our data set were supported by morphological characters, but these were occasionally subtle and/or only detectable in the males, possibly suggesting a recent divergence time [ 23].

The morphological matrix was developed for this study by coding morphological characters for Physcomitrella but otherwise follows the morphological matrix used in previous studies [ 3, 5, 54].

Few morphological characters support Afrotheria, but the inferred biogeographic story, involving continental breakup in the Cretaceous, is so compelling that it quickly gained wide acceptance.

The taxonomy of Galápagos tortoises was initially based mainly on diagnostic morphological characters of the shell, but has been clarified by molecular studies indicating that most islands harbor monophyletic lineages, with the exception of Isabela and Santa Cruz.

Zone had no significant effect for all female morphological characters of G. fultoni, but zone had a significant effect for head width in G. vernalis (Table 4).

If used appropriately, morphological characters can reveal evolutionary relationships but the students assessed did not often make the crucial distinction between homologous structures indicating common ancestry and analogous structures indicating convergent evolution.
