Who Will Baby Identify With?

Whether or not our baby will identify with me or him is a concern of my SO's. He is white and I'm black. He worries if the baby is darker, the baby won't identify with him well. This has not been a concern of mine; I mean, we will be this little baby's parents and raising him and that will be enough. But my SO is still worried. Not sure what to say to him? Advice??
