Sentence examples for shape a trait from inspiring English sources

P factors preferentially insert and mutate the Drosophila X-linked singed locus, which affects bristle shape, a trait that can be seen with a magnifying glass.

Here, we characterize variation in and test for an association between SARPs and head shape, a trait under strong sexual selection, in the stalk-eyed fly, Teleopsis dalmanni.

Using Malawi cichlid hybrids, they showed that lower jaw shape, a trait under strong directional selection [ 22], did not exhibit TS while the shape of the neurocranium, a trait not under directional selection, did.

They recommend the use of "function" only when natural selection has "shaped" a trait for some use — i.e. the trait has undergone some modification in form that makes it more suited to the use.

Linking the evolution of the phenotype to the underlying genotype is a key aim of evolutionary genetics and is crucial to our understanding of how natural selection shapes a trait.

In evolutionary biology, we might ask which factor shaped a particular trait or behavior.

To fully understand how natural selection is shaping a given trait, it is necessary to understand the constraints placed on adaptation at the phenotypic level by the underlying genetic architecture (Sokolowski 2001; Orr 2005).

The polygenic basis of wing shape and its adaptive significance (flight, host finding), combined with the relative simplicity of a two-dimensional structure that allows a precise recording and analysis of the shape using geometric morphometrics, makes wing shape a very useful trait in the study of morphological evolution [ 7, 26- 28].

Interestingly, the ChiS regulator was only present in the Vibrio strains, suggesting that transcriptional shaping by chitin could be a trait associated with this family.

A total of 138 body shape quantitative trait loci were identified in this cross, thus revealing a highly polygenic architecture of body shape in Lake Whitefish.

Those traits also shape a later trilogy, themed around summer, autumn and winter: in the first, a woman pieces together the day her husband disappeared at sea; in the second, two strangers meet in a graveyard, yet have somehow known each other for a lifetime.
