A 12 year old boy complains of achy joints usually after soccer practice. He complains of pain upon waking in the morning although pain lessens as he is more active during the day. He has been diagnosed with juvenile arthritis. What is the role of genes in the development of arthritis?

it hurts at first because " the cherry is broken" which is a thin layer of skin that breaks so the first time girls have sex it hurts and it bleeds but after the first time it does hurt again because the skin that ia torn does not break again/ grow back.
