Question: You Have Isolated A New Single Gene Mutation In Zebrafish You Call Casper Because The Mutant Fish Are Clear (no Pigments In The Scales). It is unclear why the stickleback casper mutation in exon 6 of Hps5 causes more severe pigmentation phenotypes than the zebrafish snow white mutation (Daly et al. Affordable price with superior performance. The zebrafish strain casper is homozygous for the pigment-affecting mutations of roya9 and nacrew2. This effort showed that their genome is remarkably similar to the human one, with at least 70% of human genes having a zebrafish equivalent – a figure that is even higher when only disease-causing genes are considered. Teaching NGSS is more than checking off standards. Moving to NGSS? Mutations in MPV17 , a nuclear gene encoding a mitochondrial inner membrane protein, have been associated with hepatocerebral forms of MDS. Nevertheless, genomic causal mutations of this transparent phenotype are poorly defined. The answer is literally skin deep in the fish. After a year, they developed the Casper Fish™, which lacks pigment in its skin and scales, and therefore is transparent. The ability to visualize neural circuits in zebrafish in vivois one of the most useful aspects of this model organism in neuroscience. In this activity, students engage in a game of beanbag toss—but instead of merely keeping score, they explore statistical concepts such as mean, median, mode, and range.
