In at least fifteen cases, the roof sheared cleanly from the walls along the connection between the two, and in a further seven observed instances the wall was broken along the mortar-block interface.
We also observed instances of branched muscle fibers (Figure 6D).
We observed instances of some trunk ISAs reaching the dorsal somite margin and initiating longitudinal branching prior to ISAs located anteriorly, indicating that timing of ISA remodelling is not absolute and is a highly dynamic process.
We observed instances where aggression from a nestmate immediately preceded departure on 17 nests, but this was no more likely to occur on nests containing unrelated subordinates than other nests (χ2 (Yates' correction) = −1.75, d.f.
We also observed instances of failed detection in populations accounted for by corresponding reference signals.
We observed instances of microduplications in 15q11-q13, including two novel microduplications, and microduplications in 22q11.2.
We have also observed instances where the importance of tacit knowledge and other intangible barriers was simply dismissed.
Indeed, we observed instances where Gnomon "invented" exons from intronic sequence when a complete exon was not present.
