Grades 9–12 NGSS student learning activity focused on genetics and inheritance. (a) Description of NGSS standard and proposed student activity. (b) Representative glowscope fluorescence images of 4 dpf Tg(myl7:EGFP) zebrafish larvae used to determine the proportion inheriting the green heart trait (indicated by white arrows). Tabulated data, each set obtained from a single clutch of zebrafish embryos, are matched to Punnett squares that are consistent with the observed offspring phenotypic ratios. Images were acquired using an Apple iPhone 12 Pro.
