Humanity should study the foundations of heredity. But this will be po — Genetics

"Genes embody knowledge about their niches. Everything of fundamental significance about the phenomenon of life depends on this property, and not on replication per se."

"The attitudes vary between countries, there are numerous texts for various types of biobanks, the same texts raise different interpretations in different institutions, there are new ethical opinions expressed, and mainly the novelty of questions raised by the uses of samples that are possible today, especially in genetics, and were not foreseeable at the time of sampling make the field difficult in practice."

"Modern science is proving more and more clearly that heredity plays an ever-decreasing part in the evolution of the higher creatures, that mental and moral qualities are not transmitted from parents to offspring, and that the higher qualities the more patent is this fact ‘ the child of the genius is oft-times a dolt; commonplace parents give birth to a genius."

"Most Americans still believe that there is some biological legitimacy to our socially constructed racial categories. However, our modern scientific understanding of human genetic diversity flies in the face of all of our social stereotypes."

"One prong in the approach to incorporating genetics into clinical work focuses on the parents of individuals with eating disorders. Whether the parents are involved in parent training, traditional family therapy, or other types of supportive interventions, they can be educated about genetic factors influencing eating disorders. A sensitive explanation that incorporates knowledge about complex genetic etiology (not the one gene-one disease model) and about how genes and environment interact can serve to relieve guilt in parents who have been blamed for creating the illness in their offspring (or alternatively erroneously assumed that their parenting was to blame). A genetic and biological explanation can help parents understand that their child’s resistance is not just stubbornness or deviousness, but that in his or her recovery, their child is fighting an uphill battle against his or her biology. This knowledge can empower parents to understand and can decrease frustration. Care should be taken that parents do not transform this knowledge into a new form of guilt (i.e., feeling guilty for passing on risk genes), as the roll of the genetic dice is one thing over which we have no control. Likewise, care should be taken not to allow the genetic information to impart complete absolution on parents, as parenting can always improve and positive parenting changes should also be prescribed as part of treatment."

"A question commonly posed by clinicians, families and patients alike is, how do genes work in influencing risk for eating disorders? The lay conception of genetics tends to over-emphasize the deterministic aspect of genetic risk. Modeled after Mendelian inheritance one gene-one disorder examples (e.g. Huntingtons), the misperception emerges that there is one gene for anorexia nervosa and if you have that gene you are destined to develop the condition. Clinicians are well-positioned to dispel these myths and offer more realistic albeit complicated explanations for complex inheritance patterns. By definition, eating disorders are complex traits. That means that their inheritance pattern in families does not follow traditional Mendelian patterns, and that they are influenced by multiple genetic and environmental factors of small to moderate effect. There is not one gene for anorexia nervosa or one gene for bulimia nervosa. More likely there are a number of genes that code for proteins that influence traits that index vulnerability to these disorders. Complicating the risk picture even further, these genes exist in concert with other genetic factors that may confer protection against eating disorders, along with main effects of risk and protective environments, as well as gene x environment interplay as we discuss in the following section."
