This low nucleotide diversity could result from a selective sweep linked to age-1 or from strong purifying selection at synonymous sites.
The low diversity we found could be explained by a recent introduction of the bacteria into the area [although A. phagocytophilum seropositive horses have been found in the area since 2001 (3 )] or by a selective sweep linked to the particular ticks and host reservoir in Camargue.
Not for nothing is this majestic sweep of links on the Fife coastline seen as one of Scotland's greatest new golf courses of the past 100 years.
It says much for the good doctor's creative genius that this magnificent sweep of links-cum-downland stands number three in Australia, 43rd in the world.
It was not immediately clear if the sweep was linked to the Last Bet operation that has resulted in more than 100 people placed under investigation in Italy since mid-2011, with suspect Serie A and B matches being looked at by prosecutors in the cities of Cremona, Bari and Naples.
This test was designed specifically to detect a selective sweep, as linked sites should rise in frequency around the target of positive selection, increasing derived allele frequencies.
Nevertheless, synonymous mutations can be affected by 'selective sweeps' of linked nonsynonymous mutations (Maynard Smith and Haigh, 1974).
In this context, it is possible that selective sweeps on linked loci outside the mcy genes yielded the structured mcy phylogeny (i.e. a "hitchhiking effect").
There is possibility that RAD loci's nucleotide diversity is influenced by background selection and selective sweeps on linked loci [ 37, 38].
We use a new frequency propagator method to infer selection from polymorphism time series, which is applicable to recurrent selective sweeps in linked genomes.
