Originally, back in 2010, it took Locher five months to produce a 32" x 32" pen on paper piece called Variations in Symmetry.
This genus is characterized by an extraordinarily large variation in floral symmetry (Bello et al., 2013).
Subtle variations in the symmetry of the narrow signals confirmed the changes in chemical composition apparent from high resolution 1H n.m.r.
In part, this conjecture emerged from findings that g is associated with developmental instability, as assessed by composite measures of random variations in bodily symmetry.
After sorting the filaments to consider variations in helical symmetry and accounting for the filaments that may be tilted out of the horizontal plane by up to 15°, we calculated a final map from 15,366 boxed segments of filaments.
The most compelling evidence for transgenerational epigenetic inheritance comes from studies of plants; DNA methylation-mediated silencing of the Lcyc promoter causes variations in floral symmetry in Linaria vulgaris (toadflax) that are stably inherited over many generations.
There are, however, significant variations in the symmetries, as previously found among the flexible potexviruses, but not among the rigid tobamoviruses.
Thus the clines at these loci are highly coincident, and variation in cline width and symmetry forms a bowtie around a knot of coincident centres.
The large proportion of shape variation that is taken up by the asymmetric component of variation is in striking contrast to most studies of shape variation in structures with bilateral symmetry [e.g. [ 14, 25, 29, 31- 33, 53, 66]].
