Should you choose a mate based on genetic fitness? Photo: bio.davidson.edu.
Should you consider genetic fitness as a partner?
Should your choice of spouse be left solely to your heart, or should the choice incorporate some genetic fitness phase? Obviously, if one is to regard marriage (or any other equivalent arrangement such as cohabitation) as a joint decision to share your life with someone you love, incorporating genetic criteria might seem rather troubling, if not inappropriate. But, on the other hand, if you hold the view that the main reason for your union is procreation, then worrying about genetic compatibility and avoiding inheritance of grave genetic diseases becomes a serious consideration.
Many countries already conduct genetic screening.
Genetic testing and genetic screening have become part of contemporary medicine and public health initiatives. These terms are usually used interchangeably, but the term “testing” denotes a genetic test done on an individual voluntary basis, while “screening” implies large-scale, public health initiatives. Examples of genetic testing in clinical settings include testing for the presence of BRCA1 and BRCA2 genes, to identify increased risk for breast and ovarian cancer, or prenatal genetic testing for Huntington disease. Examples of public health initiatives in screening programs include newborn genetic screening programs instituted in all states in the United States (these panels of tests range among states from 6 to 50 diseases) and in other developed countries.1,2
The impetus to identifying the genetic cause of a disease or a susceptibility implies, or should imply, the ability to act upon this knowledge:
- providing timely treatment
- avoiding exposure to environmental risks
- influencing reproductive choices
Screening should be restricted to lethal or severely debilitating diseases.
Importantly, we are not dealing here with genetic enhancement but rather avoiding the birth of babies with lethal or severely debilitating diseases.

Dor Yeshorim and Thalassaemia
The Dor Yeshorim program focusing on the ‘genetic compatibility’ of prospective couples in Orthodox Jewish communities in Europe, the US and Israel. It is compared to the premarital genetic testing programme for thalassaemia in Cyprus.

Resources for Primary Care Teaching
Teaching Resources from the Northwest Association for Biomedical Research (NWABR)
The Northwest Association for Biomedical Research (NWABR) strengthens public trust in research through education and dialogue. Its diverse membership spans academic, industry, non-profit research institutes, health care, and voluntary health organizations. Through membership and extensive education programs, it fosters a shared commitment to the ethical conduct of research and ensures the vitality of the life sciences community.
The Ethics Primer provides engaging, interactive, and classroom-friendly lesson ideas for integrating ethical issues into a science classroom. It also provides basic background on ethics as a discipline, with straightforward descriptions of major ethical theories. Several decision-making frameworks are included to help students apply reasoned analysis to ethical issues.
Bioethics 101 provides a systematic, five-lesson introductory course to support educators in incorporating bioethics into the classroom through the use of sequential, day-to-day lesson plans. This curriculum is designed to help science teachers in guiding their students to analyze issues using scientific facts, ethical principles, and reasoned judgment.
Introductory Bioinformatics: Genetic Testing
The curriculum unit explores how bioinformatics is applied to genetic testing. Students are also introduced to principles-based bioethics in order to support their thoughtful consideration of the many social and ethical implications of genetic testing. Throughout the unit, students are presented with a number of career options in which the tools of bioinformatics are used.
