In theory, alternative mating tactics may represent either distinct genetic alternatives, maintained in evolutionarily stable proportions, or conditional phenotype expression dependent on the environmentally determined state of the male.
They may represent either end of a spectrum, but they represent extremes.
Furthermore, such interactions may represent either adaptive or toxic responses to a stressor.
We also observed additional bands, migrating between 75 and 150 kDa, which may represent either incomplete cleavage products or a contamination of the immunopurified triSpike.
Animal hybridization may represent either a serious conservation concern [1] [3] or an opportunity for increased population genetic diversity [4], [5].
The few Thy1high cells expressing Krt18 may represent either contaminating cells, or cells which are in process of transition towards the Thy1low-state (see below).
Previous data suggests that normal ER+ cells may represent either relatively differentiated luminal cells with limited progenitor capacity or primitive progenitors with stem cell properties in the luminal cell compartment [4], [24], [25].
Because individuals of these two species had the same thermal history, this variation between species is not likely due to differential heat-hardening but, rather, may represent either higher constitutive, or more rapidly induced, Hsp expression in Diplosoma.
Both information sources may represent either biased or incomplete information.
But such EM sections may represent either 2D or 3D couplings, that inherently vary in size, shape, and orientation.
Fibromyalgia may represent either comorbidity or a continuous phenotypic spectrum associated with variations in central pain processing [ 1].
