The use of the pedigree mutation rates provided estimates between 600 and 2,300 years ago for haplogroups C3* and C3c, with expansion times 200 years later.
This load can be generated at a wide range of absolute mutation rates, provided the diploid retains a substantially sub-optimal mutation rate.
This problem can be sharpened by discussions of introns and of sex, because both are phenomena that, like TEs, and like an evolutionarily productive mutation rate, provide evolvability and thus need an explanation [ 16].
Therefore, a high mutation rate provides the likely explanation for the prevalence of m.3243A→G in disease cohorts.
For example, stronger selection on males is expected to improve the mean fitness of females for a given mutation rate, provided mutations have the same directional effect on fitness in each sex [ 15].
These statistics allow a reasonable estimation of the distribution of arising mutations and of the mutation rate, provided that we accept that such a distribution may be well approximated by a Gamma.
Since microsatellite markers and the D-loop sequence of mitochondrial DNA have a high mutation rates, they provide information about recent evolutionary history as compared to slow mutating genes that provide data about ancient history [ 21].
Our study examines the wheat epigenome in relation to known TEs. sRNA-directed transcriptional and post-transcriptional silencing plays important roles in the short-term suppression of TEs in the wheat genome, whereas DNA methylation and increased mutation rates may provide a long-term mechanism to inactivate TEs.
Here, we developed bz-rates, a Web tool to calculate mutation rates that provides three useful advances over existing Web tools.
In turn, this elevated mutation rate could provide an underlying genetic mechanism to explain why robustness promotes evolvability.
