Sentence examples for pressures maintaining from inspiring English sources

When polymorphism data in a closely related outgroup species is also available, the presence of shared polymorphisms may be an indicator of shared selective pressures maintaining alleles in both species, in particular for species that diverged long ago.

However, the nature of selection pressures maintaining such polymorphisms are rarely known.

These mechanisms are ruled by two evolutionary pressures: maintaining protein function and varying the antigens present within the proteins.

Consequently, this analysis cannot prove that such patterns are due to fluctuating pressures maintaining standing natural variation within a species.

We will only be able to understand the selection pressures maintaining ESAG sequence diversity within a given trypanosome subspecies once we know more about the function of these various ESAG gene families.

Widespread polymorphisms in MHC genes and ample evidence (reviewed in [ 1- 4, 13]) that MHC sequences in most species have evolved under positive selection (i.e., selection favoring new and, therefore, initially rare allelic variants) suggest that the selective pressures maintaining polymorphisms must be pervasive.

In this way, oscillating selection pressures maintain several contemporaneous colour morphs among the snail population.

Pressures maintained for less than 1 second were disregarded.

But he has so far resisted the pressure, maintaining that he is innocent.

Hence, there must be a strong, general selection pressure maintaining this trait.
