Scientists had previously believed that the old carbon was inaccessible because it had become fixed in the soil; that belief has become a magnet for new studies and controversy.
Unfortunately for the GOP and its nominee, that image has become fixed in two tracks: foolish or frightening.
In Denmark, hygge is most potent during the long winters, but exists all year round – bicycle rides can be hygge, pebbles can be hygge, blue skies can be hygge – so it is interesting that in translation hygge has become fixed to the winter months.
Secondly, the mutation has become fixed in the majority of lineages and clusters from within these groups, indicating that it might provide the organism with a survival advantage that is able to override the homogenising effect of recombination/gene conversion events.
Maybe that habit has become fixed in me.
At some point in Strictly's 10-year run, Revel Horwood has become fixed in the role of the show's panto villain.
If this happens, the red allele has been lost permanently in the population, while the remaining blue allele has become fixed: all future generations are entirely blue.
Once the translocation has become fixed within a group, complete fertility will be restored to all individuals of that group.
Once a motif has become fixed, negative (or purifying) selection will retain beneficial motifs, and subsequent mutations that become fixed by genetic drift will tend to remove neutral motifs over time.
Taking into consideration all available data, we postulate that both gr/gr and b2/b3 partial deletions when occurring outside of Y haplogroups where either deletion has become fixed, represent an infertility risk.
The occurrence of a fixed endemic ITS haplotype in one of the Estonian populations (EENN) more likely represents a relatively recent mutation that has become fixed through genetic drift, rather than indicating an extreme northern refugium.
