In B6.K > gp250 chimeras, radiation-resistant epithelial cells presented gp250 as the only ligand to promote positive selection, while B6.K bone marrow-derived antigen presenting cells presented a full peptide repertoire to restore negative selection.
Once transferred, the COXI HEG must home in order to restore purifying selection, and this requires that the mitochondria of the recipients must, at least on occasion, mix.
A lot of them rely on obtaining the selection from the Scribe element, doing something with this selection, and then restoring the selection in its original location in the document.
Selection during the selfing process decreases additive genetic variance in the breeding population that cannot be restored when selection is removed, unlike in outcrossing species, and also reduces effective recombination (Cornish 1990a, b).
Eventually, the Ariel of 1965, edited by Ted Hughes, was complemented in 2004 by a new edition, masterminded by Frieda Hughes, Plath's faithful daughter, which for the first time restored the selection and arrangement of the poems as her mother had left them.
A magnetic field of extremely high-intensity, for whicha H ≪ a 1, restores the selection rules between the oscillatory QNs.
Again, in Figure 4F, please make clear why this experiment restores negative selection.
This will eventually be restored by selection, but the population is likely to become extinct through demographic stochasticity if it remains rare for too long.
Judith Wartels, the chorale's past president and vice president, and current leader of its alto section, said that Daniel Paget, the chorale's music director since 1984, had restored the selections because "he felt their omission was a great loss to the emotional experience of the piece, and also that musically they were essential to the opening of the oratorio".
