You are a dragon breeder. Dragons can be either fire breathing or fireless, with fire breathing being dominant to fireless. Your friend has come to you for some advice. They have two fire breathing dragons that they are thinking about breeding but they are worried. Breeding dragons is expensive and fireless offspring would not sell well. Your friend knows the following about their dragons' families: Dragon 1: one of dragon 1's parents was fire breathing and one was fireless; no other known relatives were fireless. Dragon 2: both of dragon 2's parents could breathe fire; dragon 2's sister was fireless There is a genetic test for the fireless allele but it's very expensive. You would not recommend a genetic test if you knew for sure that the dragon carried the fireless allele (if you know the dragon has a fireless allele, there is not point in testing for it). You also wouldn't recommend the genetic test if you knew for sure that there was no way the dragon could be a carrier of the fireless allele. You would only recommend genetic testing if there was a possibility the dragon was a carrier of the fireless allele, but you could not know for sure without testing (it wasn't obvious some other way). Use the information given about the dragons and their families to advice your friend. Do you recommend genetic testing for either or both of the dragons (dragon 1, dragon 2)? Why or why not?
