Characterization of the ectopic projections in F → C maps^a

Animal type	Number of nodes in the map	Percentage number of nodes projecting to ectopic sites	Distance between major and minor (ectopic) sites (μm)	Orientation of the line joining the major and minor (ectopic) sites (°)
WT	151 ± 13	0.60 ± 0.44b	70 ± 11	−13.3 ± 36.0
β2	109 ± 21	0.51 ± 0.62b	112 ± 43	−4.8 ± 36.8
HetTKO	127 ± 48	7.5 ± 2.9	205 ± 44	−18.5 ± 9.2
HomTKO	130 ± 25	10.6 ± 7.5	227 ± 58	−19.3 ± 9.9
β2DKO	114 ± 30	7.1 ± 3.9	303 ± 52	−22.6 ± 4.6

^aThe numbers of ectopics are expressed as percentages of the total number of nodes in the entire map. Means and standard deviations are based on the mean figures calculated from the 20 replications.

^bIn these groups the number of ectopics is of the order of 1 or 2 per map.
