Gregor Mendal's Pea Experiment

  In 1866, a great scientist named Gregor Mendal published his finding fro a pea plant experiment.  Based on the experiment, Mendal found out the dominant and recessive heredity.  Mendel cross-pollinated smooth yellow pea plants with wrinkly green peas.  Every single pea in the first generation crop was as yellow and as round as was the yellow, round parent.  Mendel learned from this that there are two kinds of traits - dominant and recessive.  The dominant traits are the yellow color and the round shape since they show up at the expense of the green color and the wrinkly shape.  http://www.tutorvista.com/biology/gregor-mendel-pea-plant-experiment

Should Parents Able to Pick Children's traits.

  Based on the current science skills, we do not have enough knowledge to accomplish picking traits for a baby.  In addition, I do not think pick traits for babies is a bright idea becasue the genetics is the only thing to design the baby.  Otherwise, we change the baby's traits is like a way to change a person to another one.  In the movie "Gattca," the parents have choosed the traits for Vincent; however, we cannot change the traits of babies in the modern times due to we are still investigating the interesting science world.
