Etc etc etc....

That means there was 4 possible traits for everything that makes you when your parents reproduced, but only 2 made it into your DNA- wich means that 2 have nothing to do with your genetic makeup and where lost (when it comes to your DNA structure). Just because one of your parents had a trait doesn't mean that you have it anywhere.

google eye color passive/recessive for a good example.


Selective breeding.
Passive and Recessive genes.

Prime example-
ALL dog breeds that we keep as pets are descended from wolves.
However, If I breed 2 rottweilers, the pups will be rottweilers, not poodles- even though both breeds ultimately came from the same ancestors- wich looked like neither 10,000 years ago.

And yes it is completely possible to ditch a trait from a parent.
What about the people heterochromatia. Where one eye is blue and the other brown? Also the traits in the DNA would not be lost they would still be there otherwise grandchildren would not take on the appearance of the grandparents or relatives further back. Eventually both sides would appear and even those thaught lost would eventually show back up. DNA just doesn't disappear through breeding. Plus I don't think Samurai Japan has been doing it long enough for those traits to be gone since it would literally take several hundred years to become so recessive tthat it doesn't show through.
