(ii) What is the regional genetic population structure and how many genetically distinct groups exist across Australia?
DENV-3, subtype III isolates from mild and severe disease outbreaks formed genetically distinct groups, which suggests a role for viral genetics in DHF.
Genetic distance among geographic sites was generally low, but clustering analysis revealed three genetically distinct groups, that is, southern, central/south-eastern, and north-eastern locations.
About 20,000 years ago, the new analysis finds, these people began dividing into genetically distinct groups.
One offspring representing each of the 104 inferred mothers were included in a STRUCTURE14,15,16 analysis of microsatellite loci to detect the most likely number of genetically distinct groups.
An analysis of its DNA, and the DNA from 17 other mammoths, by Stephan Schuster, of Pennsylvania State University and published in the Proceedings of the National Academy of Sciences, suggests the species was composed of two genetically distinct groups.
The PHBV viruses can be subdivided into seven genetically distinct groups (tentatively named A-G) of which the two isolated of PHBV-G are the most divergent sharing ∼79% genome wide pairwise identity with all their PHBVs.
But a team of Cancer Research UK-funded scientists from the University of Manchester – led by Dr Claudia Wellbrock – has found that these genetically distinct groups of cells may actually work together co-operatively, to break away from the tumour and spread around the body.
Likewise, a STRUCTURE14,15,16 analysis based on 13 nuclear microsatellite markers suggested K=3 as the most likely number of genetically distinct groups within our European samples, but this putative structuring was unrelated to the two mitochondrial lineages or host race identity (Fig. 3).
Such animals, which contain genetically distinct groups of cells from more than one organism, are called "chimeras".
The results, posted on 8 August in a preprint on bioRxiv, showed six genetically distinct groups of Wilson's warbler.
