The parents are geno typically heterozygous in all genes.  They all express the dominant trait, while their offspring is homozygous recessive. Homozygous dominant, and heterozygous, with some expressing the dominant traits, others the recessive traits. If the genes are unlinked, so that the traits are independent, you'd have 2^4 = 16 different combinations when experimenting with 4 genes. Thats why P1 is alike and all F1 is different. Those are the reasons.

I don't believe that we should be able to pick genetics because everybody can end up looking the same.  Everybody to should look different so they can be recognize.  If we could pick genetic traits we will not tell who is who. If we kept the world as if it is now it would be better because everybody has a different look and personality.  It can be dangerous to pick genetics also because if they pick the wrong traits something can go wrong.
