Answer: Miles' belief that his family genetics are the cause of his powers "messing up" reveals his self-doubt and struggle with his new identity as a superhero.
Step-by-step explanation:
Miles Morales is a fictional character in the Marvel Comics Universe, specifically in the Spider-Man series. He is a teenager who gains superhuman abilities after being bitten by a genetically-altered spider. In the comics, Miles at times expresses concern that his family genetics might be the cause of his powers "messing up". This is because his uncle, Aaron Davis, who is also a superhuman in the comics, has powers that are unstable and difficult to control.
Miles' belief that his family genetics are the cause of his powers malfunctioning reveals his sense of insecurity and self-doubt. He is still coming to terms with his powers and his identity as a superhero, and he may feel that he is not good enough or that there is something wrong with him. Miles is also dealing with the pressure of living up to the legacy of the original Spider-Man, Peter Parker, and he may feel that any problems with his powers are a reflection of his own shortcomings.
Overall, Miles' belief that his family genetics are the cause of his powers "messing up" reveals his inner struggle with self-doubt and his desire to find answers and explanations for his powers. It also shows that he is still trying to understand and come to terms with his new identity as a superhero.
