We are all familiar with the idea of adaptation a feature produced by selection for its current use.
Previous studies have indicated a high degree of genetic heterogeneity, which is hardly affected by selection for drug resistance.
Strain NDH32 was generated by transformation of chromosomal DNA of NDH31 into WB800, followed by selection for chloramphenicol, neomycin and erythromycin resistance (strain NDH32).
The students' general expectations have a significant effect on their success, measured by selection for the national fair and the final round of the national competition.
Thus, anteriorward serial replication of the mesoderm-derived structures (shell muscles excepted) in the Monoplacophora could be driven by selection for increasing respiratory surface.
In this article, we have focused on exaptations, features that perform a function but that were not produced by selection for their current use.
Positive medium-to-high genetic correlations among harvest traits suggest that indirect gains in yield can be achieved by selection for either higher growth or survival.
The dearth of pseudogenes suggests that sequence clusters are maintained by selection for high gene-copy number, perhaps due to selection for high expression rates.
The large variations in height and weight are explained by selection for a variety of uses within the breed.
The construct was transformed into the YHΔtpx followed by selection for gentamicin resistance.
To rule out effects generated by electroporation or by selection for highly proliferative subclones, a control vector was transfected into TiB7-4 parental iPS cells.
