Upward migration of subduction-related magmas also contributes to the development of paired metamorphic belts, in which high-pressure, low-temperature metamorphic rocks are flanked on the continental side by a parallel belt of low-pressure, high-temperature rocks.
More generally, food sharing has been described as a reciprocal act of physical affiliation [8] and an essential component for the development of pair bond [9].
Considerable progress has been made in the development of pair-cross specific [ 25– 28] and consensus genetic linkage maps [ 25, 27, 28], based on use of such markers.
A major advance in NGS is the development of paired-end (PE) library construction, which generates two short reads from a single DNA fragment separated by an insert of a known size.
Experimental and fossil evidences support the hypothesis that mechanisms governing the development of paired appendages (paired fins and limbs) originated in the more ancestral median fin (Coates, 1994; Freitas et al., 2006; Shubin et al., 1997).
As noted in the section above, the Fgf receptor FGFR2b is expressed within the developing mammary placodes, and disruption of this gene in mice inhibits the development of four pairs of placodes [ 7].
Even though 24BGal4>AbdA results in the development of three pairs of ectopic alary muscles in T1/T2 to T3/A1, tip cells make their normal A3/A4 alary muscle contacts.
Although DMBA-induced murine mammary tumors containing both luminal and myoepithelial cells have been described [ 8], murine spontaneous tumor models of a bicellular phenotype are lacking, and the reproducible development of matched pairs of malignant luminal and myoepithelial syngeneic cell lines has remained a major challenge in breast tumor biology and pathology.

Yamen Saraiji led the development of a pair of robotic arms that can be worn like a backpack and controlled by a remote operator.
