Those that also improve gene function will be fixed more rapidly, those with neutral and nearly neutral consequences for gene function will be fixed more often, and those that are significantly deleterious will be eliminated only after more selective deaths.
Indeed, if a recessive character leading to saeptation is being selected for, it will necessarily be fixed very rapidly in the saeptated population, and one would thus expect a few centimorgans of the genomic region surrounding the recessive allele to become fixed with it, and hence to harbour very limited diversity, and this would be even more true for co-recessive traits.
Hence, our results suggest that historical gene flow between Oregon and non-Oregon populations may have been largely or entirely unidirectional and that novel intron-bearing alleles received by Oregon populations are likely to be fixed or lost rapidly, due to drift, resulting in reduced overall genetic variation.
If all this goes together rapidly, I'm very confident that the problem will be fixed.
It's very unlikely to be a permanent downgrade into default or the slightly higher junk territory if it is fixed fairly rapidly.
Consequently, we hypothesise that escape variants with a high selective advantage are associated with rapid progression to AIDS not so much because they are fixed more rapidly from first appearance but because they escape earlier and more frequently leading to greater loss of CTL control.
During the most recent and severe DENV-4 epidemic in Puerto Rico in 1998, viruses were distinguished by three amino acid replacements in the NS2A protein (I14V, V54T, and P101T), which were fixed more rapidly than would have been expected by drift alone.
For example, the I572F rifampicin-resistant mutation found in lines 56 and 61 has the highest relative fitness as a single mutation, but rifampicin resistance was not fixed rapidly in these two lines.
Because so many of a hotel's costs are fixed, that translates to rapidly growing profits.
