More recent, large-scale studies show similar trends; sequence variation is markedly reduced on the X chromosome in derived strains while reductions in diversity at autosomal regions are less uniform across loci [ 22, 23].
As expected from non-accumulating DNAs, the control tests show neither overrepresentation of the sequences analyzed, nor any consistent trend in sequence frequencies with respect to the mismatch load.
A comparison showed a trend of sequence variability and copy number being positively correlated, and a trend of sequence variability and length of repeat being negative correlation [ 36], but data sets from further species are needed in order assess if these trends reflect general patterns.
Therefore, in the next experiment, we also used a time series with smaller trend change sequence as a test object.
The friction coefficient of the coatings has an increasing trend by sequence of the Cu-Sn coating, Cu-Sn/Co-base coating, and Cu-Sn/Co-base/Mo coating, but an obvious difference could not be seen in the coatings.
This was based on the conception that a divergent trend in sequence similarity would be indicative of evolution from a common phylogenetic ancestor.
This analysis confirms that HA gene lineages in Mexico follow a yearly cumulative trend of sequence mutations.
In medicine, the community is preparing for personal, whole human genomes to become a part of routine care, while a trend to sequence gene panels in human increase until this happens.
The only trend between sequence changes and disease phenotype is that most cases of GSS include 129V on the mutant allele, but the presence of this polymorphism in some familial CJD cases diminishes the correlation.
The continuing reduction in the cost of sequencing suggests that the trend towards sequencing by small laboratories will increase substantially in the future.
