"Same logic to love b/w boy and girl - they are both looking for their best possible partner to sire an offspring with the best available genome code." I am left speechless at this statement. You are not wrong, but you are not right either. You have reduced love to genetics and genome code.
I wish the best possible genome code for your offspring!
