However, we also find that the Z A expression ratios are substantially less than 1, indicating that M F parity on the sex chromosome may have evolved without conservation of the ancestral Z A expression levels.
Evolving from conservation genetics to conservation genomics is not merely an extension of existing approaches, but it opens the way to asking and answering totally new questions.
Interactions between mutational biases, BGC, and weak selection can have intricate effects on sequence conservation and its inference: the rate of evolution at constrained sites can actually be higher compared with neutrally evolving sites, and conservation estimates will typically depend on the orientation of selection and vary over time.
The treatment of early stage breast cancer is evolving from traditional breast conservation techniques, employing conventionally fractionated whole breast irradiation, to techniques in which partial breast irradiation is used in an accelerated fractionation scheme.
Moreover, if a dataset has a significant number of recently evolved sequences, the conservation score of the alignment columns picked up as conserved might be an erroneous representation of the data set.
Historically, SLiMs were discovered as islands of conservation in rapidly evolving regions and, as a result, many of the early motif instances were conserved over large taxonomic ranges [ 19– 22].
The dependence on foreign oil and the lack of a backup plan, either in the form of a bolstered reserve or conservation, evolved in large part because the United States thought Saudi Arabia would again make up for any supply disruption.
For much of the last decade, Mararv managed Chinko, a remote hunting camp in the southeastern Central African Republic, similarly rich in wildlife; under his tenure, it evolved into a conservation area.
