As the difference, or genetic distance, increases, the two separated populations may become distinct, both genetically and phenetically, although not only genetic drift but also natural selection, gene flow, and mutation contribute to this divergence.
The pupil tends to constrict, and the normally clear iris markings may become less distinct.
Perhaps this is the strange, phantasmal way the language of the past calls us from exile, the way the borderlands of an old identity may become less distinct the further we move away from it, without ever fully vanishing.
Tumour uptake may become more distinct at later times compared with physiological uptake.
Moving independently, they become distinct as individuals.
Nevo says that given enough time, the basalt mole rats may become so genetically distinct that they are no longer able to breed with chalk mole rats at all in other words, he thinks his results show sympatric speciation in action.
Commercially-available antimicrobial CVCs in clinical use may become colonized with distinct microbial flora probably related to their antimicrobial spectrum of activity.
The clinical presentation of ATD-associated liver disease is highly variable and may become apparent in distinct forms during infancy, childhood years, adolescence, or at 50 65 years of age [ 1].
Groupon too may become less of a distinct business, and more of a way of offering discounts that loads of businesses adopt, it could even become a classified revenue replacement for whatever daily newspapers are still in businesses.
Moreover, distinct autoantigens may become novel therapeutic targets in disease, e.g., blocking GAPDH-mediated cell death in pathological conditions.
Citrus tristeza virus (CTV) represents an example of a virus that causes persistent infections in a long-lived, economically important hardwood perennial crop plant, so that with time a single host plant may become infected by multiple, phylogenetically distinct CTV genotypes.
