In February of this year, the Human Fertilization and Embryology Authority in the United Kingdom approved a request by the Francis Crick Institute in London to modify human embryos using the new gene editing technique CRISPR-Cas9. This is the second time human embryos have been employed in such research, and the first time their use has been sanctioned by a national regulatory authority. The scientists at the Institute hope to cast light on early embryo development—work which may eventually lead to safer and more successful fertility treatments.
The embryos, provided by patients undergoing in vitro fertilization, will not be allowed to develop beyond seven days. But in theory—and eventually in practice—CRISPR could be used to modify disease-causing genes in embryos brought to term, removing the faulty script from the genetic code of that person’s future descendants as well. Proponents of such “human germline editing” argue that it could potentially decrease, or even eliminate, the incidence of many serious genetic diseases, reducing human suffering worldwide. Opponents say that modifying human embryos is dangerous and unnatural, and does not take into account the consent of future generations.
A sample that proportionately reflects the relevant diversity of opinions in the population from which it is drawn is known as a representative sample.
A representative sample refers to a subset of a population that attempts to accurately reflect the characteristics of the larger group. In order for a sample to be a representative sample, the sample group must represent the population as a whole. Hence, a representative sample is a sample type which proportionately reflects the relevant diversity of opinions of the target population. For example, a classroom of 30 students with 15 males and 15 females could generate a representative sample that might include six students: three males and three females. In order to obtain a representative sample, the most appropriate sampling method is simple random sampling.
