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 zygous 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?
