The phrase "a major differentiation between" is correct and usable in written English.
It can be used when discussing significant differences or distinctions between two or more items, concepts, or groups.
Example: "There is a major differentiation between traditional marketing strategies and digital marketing approaches."
Alternatives: "a significant distinction between" or "a key difference between".
In fact, given that PC1-3D is the axis of major differentiation between Saimiri and Cebus, and that BR is dislocated to a more posterior and lower position while LD is dislocated forward that explain why the linear distance between the two landmarks is basically the same in both genera, despite the huge size difference between them.
This confirmed that, outside of the pericentromeric X-chromosomal region, there was no major differentiation between the forms in the populations studied here, in contrast to the interform differentiation previously seen in Mali.
This is also the axis of major differentiation between the two genera and in fact the only one where they do not overlap and present a significant difference on a series of t-tests performed upon each of the first 40 PC's of the 3D analyses.
The major differentiation is between isozymic group 1 (indicas), characterized by a superficial, thin, highly branched root system with a low R/S ratio, and isozymic group 6 (japonicas) characterized by a deep, thick, less branched root system with a high R/S ratio.
While the major differentiation was between samples separated by the south north geographic line (Table 3), significant differences in gene frequencies were also found among samples within both the southern and the northern regions (Table 5).
Consequently, it may be considered that the levels of distress, despite constituting a major source of differentiation between males and females, is in no way a means to discriminate or differentiate between the three categories of abuse considered within this study.
In all of this, the arguably greatest error in terms of international reality would be Mrs. Merkel's appearing to suppose there is some major strategic differentiation between the two Russian leaders, and to cast Mr. Medvedev as a relatively benevolent force.
Cluster analysis using approximately 200 control (non-candidate gene) SNPs, dispersed throughout the genome (Table S1) identified marked structure within each collection (Figure 2) attributable to two major sources: differentiation between the molecular forms of A. gambiae, and between individuals possessing different inversion polymorphisms.
These genes were responsible for major morphology differentiation between cultivated crops and their progenitors, such as branch (tb1) and glume architecture (tga1) in maize [ 52, 53], seed size (fw2.
