Sentence examples for selective hypothesis from inspiring English sources

falciparum and P. reichenowi; P. vivax and P. knowlesi; P. yoelii and P. berghei) were compared for a set of 43 candidate ligand genes considered likely to be under positive directional selection and a set of 102 control genes for which there was no selective hypothesis.

In contrast, it is unfortunate that the Tay sachs selective hypothesis remains largely untested almost two decades later.

The link between restricted pleiotropy and the emergence of phenotypic complexity provides both a mechanistic interpretation of complexity and a selective hypothesis underlying its evolution.

There is increasing evidence supporting the selective hypothesis for lighter skin, as it allowed higher levels of vitamin D photosynthesis in regions with lower levels of UV irradiation (Jablonski and Chaplin 2000, 2012).

So there seems to be no trend in parasites and symbionts in general, an observation that suggests extra caution with regard to the selective hypothesis of TAS loss in intracellular microbes.

While each analysis was chosen to investigate selective hypotheses utilizing different aspects of the data, none of these analyses were perfect in application.

We thus analysed our data regarding the two main selective hypotheses proposed to account for the special pattern of LC T*Pdistribution, gene-culture coevolution (gcc) [8], [9] and calcium assimilation (cal) [10].

One key to differentiate with more confidence the alternative selective hypotheses would be to get more samples from the Iberian Peninsula because in this particular region, LP frequency is expected to be very low under cal or lbk hypotheses and certainly higher under gcc.

Two alternative selective hypotheses could explain the significant departure from neutrality of HBD: first, strong purifying selection that would purge any new deleterious mutations and second, a complete selective sweep in which an advantageous variant reached fixation.

When two genes are in different strands the stop codon mechanism helps in explaining the abundance of different phases but we require additional selective hypotheses to explain phase variation.
