Can anyone answer this genetics question and show work (punnet square)? Thank you?
An allele for purple flowers is co-dominant with the allele for pink flowers. The heterozygous phenotype is a purple and pink flower known as a sunset flower. Gene two codes for thorns (T) or no thorns (t). If a homozygous thorned sunset flower is crossed with a non-thorned sunset flower, what are the expected F1 phenotypes? What would be the resulting F2 phenotypes and ratios if two of the thorned sunset F1s were crossed?

We finished this in biology, but it wasn't in such detail. It was fairly easy, like: a pure black cat and pure white cat breed. Black is dominant color in cats. Make punnet square. Calculate percentage of black and white offspring. That's easy, since you just write like: BW, BW, BW, BW - 100% are black. Of course, it wasn't that easy - we had hybrid cats, pure cats, flowers, incompelte dominance, but we didn't do anything related to ratios and phenotypes and F2 (what is F2). I don't know all that. but just make a punnet square. Like purple flowers are pure (or what?) and same with pink. We have to know if it's pure or not, then make a square. Simple!
And also, why is this in chemistry?
Thanks,
