Do parents and children have any thing genes common....

Tweet

I have observed that mostly daughters are attracted to their fathers and son's are attracted towards their mothers..every one knws children and parents have a very pious relation among them,still one of my friends said that their may be some genetic feelings involved in this relation.As A son is attracted to mother because he is male and mother is female.. Some times it makes me feel so odd..what you people say.. how can i satisfy him,give me a very solid and thoughtful anwer please...
