You’re an orchid breeder and have noticed that you have a few plants that display a totally novel golden coloring pattern. This gold coloring has basically made you a LEGEND in your horticulture club, and now your best friend wants to use your sweet orchids in their wedding. Obviously, getting a purebred line would be ideal for cranking up production... because your pal is going to need A LOT of flowers. But this is proving to be a challenge; every time two golden orchids are crossed, you end up with a fair number of gold flowers, but still a significant number of orchids featuring the standard white coloration. In your most gold orchid self cross, you ended up with 57 gold and 27 standard orchids. All other such matings gave similar phenotypic offspring ratios. What’s going on here?

You will create a molecular clock model for an arthropod gene. follow these guidelines to make your model: . your timeline will span from 90 million years ago to the present. the common ancestor in your model is an arthropod that lived 90 million years ago. the gene that you'll track codes for a protein in the species venom . the dna sequence youll track contains 10 nitrogen bases. you can choose the order of the bases and where the mutations occur. this gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. to build your model,/ calculate the estimated time period it takes for 1 base pair to mutate. the first time period will only show the common ancestor. at the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences. the first and third descendant species will survive for the rest of the timeline. the second descendant species was extinct 50 million years ago. calculate how long it will take for one full base pair mutation to occur. explain your reasoning by constructing a mathematical equation
