Two genes meet. What are genes and how do they affect our lives?

Genetics is one of the most useful sciences for humanity. It helps to reveal the ancient secrets of history and geography (for example, were the Neanderthals our ancestors and, if so, what are we storing their properties in ourselves?) But the main thing that everyone expects from genetics - ordinary people, governments, and genetic engineers themselves are solving practical problems, primarily health: when they will find a cure for cancer, and will they learn to treat other genetic diseases, is it possible to prevent the manifestations of Alzheimer"s disease And even keep youth to people. With the opening of a powerful CRISPR gene correction mechanism, these expectations will soon become a reality.
But nevertheless, the ability to intervene in genes does not give (so far) to scientists to reveal the secret of genes. What is a healthy person, can genes make genes ideal. Is it possible to create an ideal person and society, and what is the ethical responsibility of science for the possible consequences of genetic engineering intervention in life is an equally important circle of issues that the author does not disregard
