Question

Researchers at Boston Children's Hospital developed a translucent mutant of this model organism in 2008, called the "Casper" mutation. For 10 points each:
[10e] Identify this aquatic model organism used widely in pharmacology and toxicology due to its rapid embryo development. Its colloquial name comes from its characteristic striping pattern.
ANSWER: Zebrafish [or Danio rerio]
[10m] Zebrafish are used in the research of this signaling pathway involved in transmitting information for cell differentiation. Robert Riddle was criticized for giving a video game-inspired name to a key signaling molecule in this pathway.
ANSWER: Hedgehog Signaling Pathway
[10h] One of Sonic Hedgehog's functions is its role in the induction of ventral cell types in this embryonic precursor to the CNS in vertebrates. Failure to properly close this structure can result in spina bifida or anencephaly.
ANSWER: neural tube
