The science in The Big Bang Theory, the secrets of genetics

Our science editor, Miguel Ángel Sabadell, analyzes one of the chapters of the famous series The Big Bang Theory , to explain the secrets of genetics. Why can the children of two beautiful people be ugly? What if we created a bank of sperm and eggs from the smartest people in the world? Would we make sure the offspring were especially smart?

Well, the truth is that in the mid-1980s a businessman had this idea: ask the smartest people on Earth to sell him several million of their sperm .

In this way, those women or couples who wanted could buy a few of those sperm to conceive a supposedly intelligent child. The business was based on the assumption that smart parents routinely give smart children.

In the end the matter was not a big deal, despite the fact that many women and couples bet on it. A couple of decades later, attempts were made to sell model eggs over the Internet. Here the business is more justified: the appearance is totally defined by the genes . What is not certain, as anyone can see just by looking around, is that handsome parents have handsome children.

In The Big Bang Theory , the theme of genetic chance is reflected precisely in the first chapter of the series when Sheldon and Leonard, brilliant physicists but inept in terms of social relationships and less with women, visit a high IQ sperm bank with the idea of bringing children as intelligent as they are into the world. Sheldon tells Leonard about his concern and that is that the physicist lamented that his DNA did not guarantee the intelligence of his offspring. He used as an example his twin sister Missy, not at all brilliant (and less by his side, of course). So we learned that intelligent parents do not have to be born intelligent children.

Legend has it that Einstein faced this dilemma. When he was an old man, a beautiful young woman, who could not be said to be a promising candidate for the Nobel Prize, approached him. In a sweet voice she told him that she would like to have a child of hers. The reason? Very simple. Thus they would have a child with the unparalleled beauty of the mother and the tremendous intelligence of the father.

But the physicist said no. Einstein replied:

– My dear lady, what would happen if you took out my beauty and your intelligence?

Slaves and Disabled: Forced Medical Test Volunteers

The main problem to carry out medical research is to have willing volunteers for it. And if they come out for free, much better. This is the story of unethical behavior in medical research.
