With sportive lemurs, subspecies were traditionally defined based on slight morphological differences, but new genetic evidence has supported giving full species status to these regional populations.
Two distinct switchgrass ecotypes, lowland and upland, have been recognized and are generally defined based on their morphological characteristics and habitat preferences.
Subspecies have been defined based on phenotypic (e.g., morphological, ecological, and behavioral) and genetic criteria (Mayr 1942; Amadon 1949; Futuyma 1998; Patten and Unitt 2002; Haig et al. 2004a; Zink 2004).
From the 224 accessions evaluated, three accessions without previous information (204, 205 and 215) had their genomic constitution defined, while 13 (5.8%) disagreed with the information available about genomic constitution defined based on previous published or characterized by morphological descriptors, including accessions 7, 10, 11, 28, 68, 72, 79, 102, 195, 201, 202, 203, and 219 (Table 1).
Nineteen morphological characters were defined based on the discontinuous variation of the female reproductive tract (Table 2).
However, there is a remarkable degree of concordance between the units defined based on mitochondrial DNA [ 12- 15] and those observed by morphological analyses [ 19- 21] and multilocus nuclear data [ 16- 18].
A previously published data set based on morphological data [ 15] was used for simultaneous analysis of morphological and molecular data.
In our ML tree, many sections, which have previously been defined based upon morphological characteristics, were not verified as monophyletic.
These species were defined solely based on morphological characteristics, such as cell size, colony formation, and sheath characteristics.
Traditionally, two main genetic groups, "Criollo" and "Forastero", have been defined within cacao based on morphological traits and geographical origins [3].
