The number of residues that are completely conserved across both major subgroups is small.
One frequent hypothesis is that the area of greatest genetic linguistic diversity within a language group is the point of origin; on this criterion, this would be in the mountains of northeastern India, southeastern Tibet and northern Burma, where the four major subgroups meet and there are some additional smaller subgroups as well.
They include over 200 languages falling into four major subgroups (Western, Central, Sal, Eastern), with various additional smaller subgroups (Bradley 2002).
Ultimately, hackers separated into two major subgroups: 'whitehats', who lived by an ethical code much like their predecessors; and the 'blackhats', who simply lived to hack systems.
We also developed subgroup-specific PCR primers for the major subgroups of Acidobacteria, except for subgroup 4. Subgroup-specific primers S1, S2, and S3, which targeted subgroups 1, 2, and 3, respectively, showed high coverage for their target subgroups and low tolerance for non-target sequences.
Based on their hydrocarbon profiles, these cyanobacterial species were classified into 5 major subgroups.
IBD is divided into two major subgroups: ulcerative colitis (UC) and Crohn's disease (CD).
These have been carefully designed to maximize the accuracy of our surveys as a whole, as well as for all major subgroups surveyed".
Recent genomic analysis defined four major subgroups of medulloblastoma.
This resulted in 165 major subgroups of functional phenotypic specificity.
