Three dichotomous morphological characters including antennal flagellum, hind-leg femur, and terminal abdominal terga were determined.
Parallel and convergent evolution of various morphological characters (including those traditionally employed to circumscribe the families and genera) have occurred in the Siphonocladales.
An array of morphological characters including plant height (PH), grain number (GN), panicle length (PL), primary branch number (PBN), secondary branch number (SBN) of the two parental lines and the F2 population were investigated at Changsha in 2011.
The morphological characters, including perennial herb, racemose inflorescence, 4 lateral united petals, 4-carpellate ovary and one ovule per carpel, also support membership of I. pandurata in this subgenus.
Because the closely related L. corrugis has overlapping morphological characters, including similar colouration in the cap and stem, it has been difficult to reliably distinguish between the two species.
Carrano et al. [46] examined the relationship between a suite of morphological characters (including snout breadth) and dietary preference in hadrosaur dinosaurs.
The median value for point estimates of heritability for morphometric characters, length, and weight was 0.52 in this study, a value higher than the median value of 0.29 observed from a meta-analysis of heritability for all morphological characters (including morphometric characters, length, weight) across salmonid species [41].
Slides were then observed and photographed under a ZEISS Axioskop compound microscope for morphological characters including overall shape and size of pollen grains, the number, shape and arrangement of wall apertures, and the structure and orientation of the exine surface [68], [69].
A morphological cluster analysis was conducted on population means of all 11 morphological characters including the number of dorsal spines.
This hypothesis is supported by a cladistic analysis of small subunit nuclear ribosomal DNA (18S rDNA) sequences in conjunction with morphological characters (including nematocysts) [ 2].
