Dor Yeshorim

[2] The same interview quotes a New York neurologist who credits the near-total disappearance of the condition from the ultra-orthodox community due to Dor Yeshorim's involvement.

[2] In 2016, Dor Yeshorim received media attention[3] when a rap video of two schoolgirls beat-boxing about their marriage prospects was shared in the Orthodox Jewish community.

[7] Dor Yeshorim screens only for recessive traits that give rise to lethal or severely debilitating disorders, providing prophylactic, rather than diagnostic services.

When two Dor Yeshorim clients contemplate marriage, they exchange sample ID numbers and birth dates and each contacts the organization.

In this way, complete privacy is guaranteed; not even Dor Yeshorim employees are aware of who was found to be genetically incompatible unless the clients desire otherwise.

[11] For convenience, Dor Yeshorim provides yearly testing sessions at Orthodox Jewish schools for students who are approaching marriageable age.

By March 2006, Dor Yeshorim had achieved wide support in the Orthodox Jewish community and among its leaders, and had become household name that was taken for granted.

[2] There has been criticism leveled against the method used by Dor Yeshorim by Moshe Dovid Tendler, a professor of medical ethics at Yeshiva University.

[13] Dor Yeshorim was also criticised for allegedly seeking to convince the Jewish community it must, for “religious reasons”, use its service, by circulating a letter from Bezalel Rakow.

These diagrams, known as Punnett squares , are used to illustrate the method of trait transfer to offspring according to classical Mendelian genetics . In the Punnett square to the left, two heterozygous individuals (carriers) can potentially form three types of offspring: homozygous positive, heterozygous carriers and homozygous negative, in the ratio of 1:2:1. Homozygous positive offspring (highlighted in red) will completely express the particular recessive trait, in this case the genetic disorder. In the Punnett square to the right, a heterozygous carrier individual and a homozygous negative individual can potentially form two types of offspring: heterozygous carriers and homozygous negative, in the ratio of 1:1, and are necessarily unable to produce any affected offspring, barring a new random mutation . It is the situation depicted on the left, in which couples have the potential of producing affected offspring, that Dor Yeshorim attempts to prevent.
