Is this true about mixed children/babies

I’m mixed with white and black. A close friend of mine is mixed with Native American and black. A co-worker of mine mother was Hispanic with long dark hair and light skin and her father was white and had blonde hair and blue eyes. I heard a few times from people about interracial couples that if the father had darker features such as hair, eyes and skin would it show in the child more. A few people have claimed to me that my father isn’t my father because I didn’t “look like him”. With my close friend he got a white girl pregnant who had blonde hair, blue eyes. People claim the same thing to him that it’s not his child. To me it’s a bunch of bs because my mom having blonde straight hair and light skin, and my father had brown tight curly hair, with dark skin. People would question why I didn’t look like my father. I’m very offended now.
