Sentence examples for by selection for high from inspiring English sources
This is in agreement with an ovine animal model [ 49], which also used sheep mammary gland epithelial cells to identify molecular mechanisms that are affected by selection for high and low SCS in two divergent lines of sheep selected by applying a selection strategy based on conventional breeding values.
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.
In an effort to increase stress tolerance, there have been attempts to artificially increase the concentration of GB in plants by selection for high accumulating species, genetic engineering, or exogenous application.
This is consistent with the notion that both characters are affected by selection for high rates of gene expression, although the relative placement of slow and intermediate growers indicates that this selective pressure is not the only factor at play.
Migration during the growing season is driven by selection for high quality forage in a variety of ungulates, particularly when nutritional requirements associated with reproduction are peaking and animals are likely seeking out regions with emerging vegetation to provide high quality milk for offspring [41].
In such cases the expansion of gene families is driven by selection for high expression [ 2].
Such a trend could be explained by selection for higher gene dosage that drives the duplication of developmentally regulated genes.
Thus, sperm competition by males may benefit the female via two different mechanisms: first, by cryptic selection for high quality males and second, by selection for highest quality sperm within each ejaculate.
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.
Second, the W → S versus S → W bias can be shaped by positive selection for high GC content in CGIs due to their role in gene regulation (Strathdee et al. 2004).
According to FAO, one third of all livestock breeds have either perished or are threatened with extinction, due to intensive selection for high production by means of artificial insemination and embryo transfer and spreading of a small number of genetically narrow high-performance breeds around the whole world.
