The starting material for the F2 progenies were the F1s described, which were crossed reciprocally with other F1 plants in a randomized block experimental design (two arrowhead lines in the middle of Figure S1).
Double-arrowhead lines are the livestock migration routes.
The physical map here is a graph consisting of nodes and arrows (only one arrowhead per line) connecting the nodes.
Arrowheads still line the streambeds.
In this example, the H3K9me3 signal shows two regions of enrichment (arrowhead, dashed lines), yet a third connected domain of compact chromatin can be discerned that is depleted in the mark.
Step 5. Strip all arrowheads from lines.
Yellow line (arrowhead): the moment the VFI frame was acquired.
The open arrowhead and dotted line indicates p53 activation in region 2 prompted by meiosis.
These vesicles showed short-range motility at 2.1 ± 0.67 μm/s (Fig. 4D, a kymograph shows motility as a diagonal line; arrowhead).
Also note that the vax2 domain in control is broader than in the rx2 BMP4 embryos (arrows) in which it is more prominent in the optic stalk region (arrowhead) (the dotted line indicates the optic fissure).
