My mother is a geneticist, and from her I learned that despite our differences in size, shape and color, we humans are 99.9 percent the same. It is in our   36   to see differences: skin, hair and eye color, height, language. But also in our nature, way down in the DNA that   37   us human, we are almost the   38  .

I believe there is more that unites us than   39   us.

My mother came to the US from India. She is   40   enough that she got her service  41  in a diner in 1960s Dallas. My father is a white boy from Indiana whose   42   came from Germany in the mid-1800s.

 It seems   43   to admit now, but I never   44   that my parents were different colors. One day, I watched my parents walk   45   the street of our church together. They were   46   in the service that day, and as they walked, I saw their hands   47   together in unison(一致地). I noticed for the first time how dark my mother was, and how white my father was. I knew them as my parents   48   I realized their skin color. I'm sorry to say that now when I see a mixed-race    49   walking down the street, I see the "mixed race" first and the "couple" second.

When my parents married in 1966, there were   50   places in this country that had laws  51   mixed marriage.   52  , my white grandfather,   53   father had been a typical racist, was not against their marriage.

Some of us are men, some are women. Some are young, some old. Some of us are short and others   54  . Some right-handed, some left-handed. We have lots of differences; we are all   55  . But deep down inside us, down in our DNA, we are 99.9 percent the same. And I believe we need to remember that.
