Sentence examples for variation was maintained from inspiring English sources

Elite thermostatic water bath was used, in which continuous stirring of water was carried out with the help of electric stirrer and temperature variation was maintained within ±0.1 °C.

In that system, the variability of the colour polymorphism in the hybrid population was substantially higher than that in the pure populations, suggesting that morphological variation was maintained by hybridization [ 58].

Thus, the sexual antagonism hypothesis could explain why variation was maintained at the DDT-R locus and why DDT-R did not fix despite its female benefits, but this remains to be tested.

By using empirically derived estimates of male and female fitness to quantify the magnitude of intralocus sexual conflict at this locus [ 23, 24], we find that polymorphism in resistance is maintained over a wide range of values, which contrasts with previous models [ 15– 18] where genetic variation was maintained only in limited parameter range.

This indicates that individual common genetic variants of this size or greater do not contribute to personality trait variation, which has important implications regarding the genetic architecture of personality and the evolutionary mechanisms by which heritable variation is maintained.

Furthermore, Johnston says, "how genetic variation is maintained is fundamental to many different real-life problems".

Evolutionary biologists have long wondered why genetic variation is maintained, when there should be a "best" variant for each gene.

Yoshida et al. [44, 45] have investigated the nucleotide diversity in the Adh1 and Adh2 gene regions of O. rufipogon in order to clarify the mechanisms by which DNA variation is maintained.

Researchers in our lab are motivated by a desire to further our fundamental understanding of the evolutionary dynamics of how species are formed, the origin of reproductive isolating barriers, mechanisms by which genetic variation is maintained, and the underlying genetic architecture of adaptive traits.

The Hardy Weinberg principle provides the solution to how variation is maintained in a population with Mendelian inheritance.

Understanding how this variation is maintained, and how it is utilized (or tolerated) by biological systems, depends on linking it to variation in phenotype.
