2. You're a beta fish breeder and have noticed that you have a few fish that display a totally novel ruby red coloring pattern. This ruby red color has since become is very popular in your Etsy store, but you are STRUGGLING to develop a purebreeding strain. Like, every time two ruby red betas are crossed, you end up with a fair number of ruby reds, but still a significant number of betas featuring the standard-type coloration. In your most recent ruby red x ruby red mating attempt, you ended up with 57 ruby red betas and 28 standard betas. All other such matings gave similar phenotypic offspring ratios. Explain what's going on here. (<4 sentences)

given that proteins are manufactured by ribosomes and (in eukaryotes) are often subsequently dumped into the lumen of the rough endoplasmic reticulum (e.r.), what problems might transmembrane proteins present in terms of shuttling them to their appropriate location? In other words, what can cells do to ensure that nascent hydroPHOBIC proteins make it to their final destination in a largely hydrophilic environment? Please number answers. Please do not screenshot a handwritten response. Please do not upload a handwritten cursive response. Text only. Please do not copy and paste. Thank you.
