These five genera have long been defined by their morphological differences (e.g. storage of products of haemoglobin degradation in the case of Haemoproteus, Parahaemoproteus, Plasmodium and Hepatocystis), variations in their life cycle (e.g. asexual replication stage in erythrocytes for Haemoproteus, Parahaemoproteus and Plasmodium) and host and vector specificity [ 4, 5, 7, 8].
Thus, it is also likely that more subtle changes in gene function or regulation underlie their morphological differences.
Because of their morphological differences, satellite cells will detach from the dish before the flattened and larger fibroblasts.
The ovaries were separated by microdissection from the mesonephros, decapsulated with fine needles according to their morphological difference in prechilled PBS (10 mM, PH, 7.4) under the stereomicroscope.
Cohorts of transgenic mice with a broad age span were analyzed, since age-related differences for Aβ deposits and morphological variants of tau aggregates have been reported for these mouse models.[ 25, 30] In APPPS1 mice, HS-68 strongly labeled the Aβ deposits and different types of aggregates could be distinguished, both by their morphological appearance[ 31] and by distinct HS-68 fluorescence.
The breeds are classified by their morphological characteristics rather than their local origins.
Their reported morphological differences [ 18] are likely geographic intra-specific variations.
Moreover, because many of the newly described species are differed only by trivial morphological differences, Weber et al. (2011) suspects that the diversity in Primulina is likely overestimated.
The complex issue of the traditional distinction between natural species defined by interfertility, and artificial species defined by morphological differences, also required a full chapter of analysis in which he sought to undermine the absolute character of the interbreeding criterion as a sign of fixed natural species (chp. 8).
The differences in behaviour are facilitated by subtle morphological differences; firecrests have broader bills with longer rictal bristles (which protect a bird's eye from food items it is trying to capture), and these features reflect the larger prey taken by the species.
This is also reinforced by the morphological differences (e.g. differences in cell size and number of nuclei, lack of F-actin ring) observed in the multinucleated cells generated in presence of IL-32 or RANKL.
