"my baby isn't going to look anything like me"

my mother in law seems to believe that her grandchild is going to look just like her and her son because they have ALL of the "predominant genes" FIRST OF ALL its called dominant genes and recessive genes NOT predominant. second of all I have black eyes,tan skin, dark brown curly hair and I'm short. my boyfriend has straight hair and is pale and is 5'11. all of my genes are dominant. ugh like who are you to tell me MY baby isn't going to look like me lmfaoooo. ugh sorry just needed to rant to someone who might understand what I'm going through.
