Genetics plays such a large part of our lives and we know so little about it. Scientists have succeeded in mapping the entire human genome. That means we know all of the letters that make up us. We do not know what it means.
First, you may need a little background information to understand this discussion. There are four bases used in DNA. These same four bases are used in the DNA of all life on earth. They are: A - Adenine, T - Thymine, C - Cytosine, G - Guanine. We know the letter sequence that makes up the entire human DNA pool. Some of the genes we do know. We know that certain genes are on chromosome 1, some on chromosome 2 and so forth. We do not know what all the genes are on all the chromosomes.
But in knowing all the genes, we would still only know half of the available information. The genes we know all occur on one side of the two sided DNA. We have no idea what the other side is for. Nature does nothing in a vacuum. The other side must mean something.
One theory for the other side is that it works on our personality. It determines if we are a sprinter or a distance runner. It determines if we attack things or hang back. Or at least, that is what the theory says. I watched a TV show on this a couple of years ago. The British Army is using the DNA data to group soldiers. They are finding it helps in designing training programs to work to a soldier's strengths.
To me, this idea is too simple. There must be some reason for having the second side of the DNA. The reason has to be something that enables life to exsist and succeed. The theory of personality may have some validity, but it just does not seem to answer all the questions. The biggest is what does that have to do with succeeding at life.
Also with genetics, we inherit a tendency to get certain diseases. If your parents have had cancer and your grandparents had cancer, you will probably get cancer. A friend of ours has cancer and will probably die from it. She seems to have DNA most similar to her mother's, as her mother also has cancer. Nobody else in her family has the same genetic makeup as she does. She is a good person. It is a shame to see a good person like her have to struggle with a disease like cancer. It would be better spent on a person who contributed nothing to society. But, I suppose somebody loves that person too.
The long and short of it is, your genetics determines to a great extent what happens to you in your life. So, it would be important to know your genetics and understand the interplay between all the letters that make up the genes in you. Unfortunately, or maybe fortunately, we cannot know our DNA at this time. To know everything would probably cause more harm than it would cause good.
