▼ Let's say I look beautiful, my gf looks ugly, how is our baby will look like?

 The combination look, sometimes the baby took some traits from you, and sometime they took the trait from the girls. So the combination of the traits like...thin eyes, big eyes, you pick one or another. Then how nose is in between the eyes, is symmetry or sometimes some people are not symmetry as straight. Is the eyes have double lid to see bigger, is the eyes around edge when eyeliner at, its wider?

Look the eye liner.

Not everyone is gonna be born always looking brilliant ways you say you pick and choose your genetics traits.

But although you cannot change that traits of passing down genes, like appearance, a lot of pregnant women what they will do, its to listen to the classic music, when they conceive the baby, or watching some nicer films, to educating the baby starting in the womb.

In other words, there are people doing this "Epi-genetics" stuffs. The doctor like Bruce Lipon, is one of the advocating a lot on this Epi-genetics.

I want something is born to be perfect stuffs.

Then you find a gf that is a pretty looking, and seriously didn't modify her look with the plastic surgeon, you check her time like no make-up.

Is the IQ matter?

IQ? you mean smart parents gives birth to the smart children, what if retarded parents given child birth is to be normal IQ? ... ...I think do the education and try not to be so superficial, but finding a mature person does a mature things, you both will evolve not to fighting things too trivial in life so your next half life, married life, you will both evolve with more maturity awareness that is coming to you, when you married together.
