You come across a gene called eyeless in Drosophila. Given what you've learned about gene naming, what is the most likely function of this gene product? to facilitate eye development to repress eye development to determine eye color
You are a researcher studying sleep signaling in zebrafish. Based on similarity to the human melatonin receptor sequence, you have a few fish gene candidates that might be functioning as melatonin receptors. Is it more appropriate to use reverse or forward genetics in this case? reverse genetics forward genetics
Let's say you generate three CRISPR zebrafish strains, each with a deletion of one of your candidate melatonin receptors, and none of them have a sleep phenotype. You decide to cross these mutants together to generate a triple knock-out. What hypothesis are you testing? You are hypothesizing that these genes are essential. You are hypothesizing that these genes act redundantly.
