In Gregor Mendel's pea plant experiment, he cross pollinated smooth yellow pea plants and wrinkly green pea plants. This is the parental generation (P). They are all alike because they are all purebred. When they cross pollinated however, they created the first generation (f1). They all ended up being like one parent plant than the other, all yellow and smooth. This is because they are heterozygous and the yellow and smooth trait were dominant genes whereas the green and wrinkly trait were recessive which made them all yellow and smooth but still carrying the recessive genes.

I don't think that parents should be able to pick the traits of their babies because they could harm the baby since it isn't natural. Changing the genes of the unborn baby could cause genetic diseases to take effect on them when they are born. When you give birth to a baby naturally, there's a chance that the babies won't take on any hereditary diseases. But when you purposely mix up the genes to create perfect traits for the baby, the genes could create some genetic diseases that could be avoided.
