We are all born with a unique genetic blueprint, which lays out the basic characteristics of our personality as well as our physical health and appearance... And yet, we all know that life experiences do change us.
The fact that plant science would be very important was evident to me and a few other people in the 1970s. What you could see was the great genetic cell biology and molecular biology coming out of the biomedical sciences would be applicable to plants, and it would be important to the world to apply this, and that St. Louis was the place to do it.
I'm very proud to be black, but black is not all I am. That's my cultural historical background, my genetic makeup, but it's not all of who I am nor is it the basis from which I answer every question.
I was always fascinated by engineering. Maybe it was an attempt maybe to get my father's respect or interest, or maybe it was just a genetic love of technology, but I was always trying to build things.
You're not a product of your nature. That is your genetic makeup or your nurture, the things that have happened to you. Of course those things affect you powerfully, but they do not determine you.
I was in Vietnam, and I was exposed to Agent Orange. And there's a high relationship between people that were exposed to Agent Orange and the kind of lymphoma that I had. The prostate cancer was genetic in my family. My father had prostate cancer, my - three of my four uncles had prostate cancer.
Identical twins are ideal lab specimens for studying the difference between learned and inherited traits since they come from the womb preloaded with matching genetic operating systems. Any meaningful differences in their behaviors or personalities are thus likely to have been acquired, not innate.
With the advent of genetic engineering the time required for the evolution of new species may literally collapse.
Every batch of sperm represents an opportunity for genetic typos - called de novo mutations - to be passed on. A 20-year-old man and woman will each pass on about 20 de novo mutations to a baby they conceive. By the time the couple is 40, a woman's total has remained at 20, while a man's has jumped to 65 - and it keeps climbing from there.
Some genetic variants can be informative about one's risk for Parkinson's disease and Alzheimer's disease.
