A new genetic analysis focusing on Jews from North Africa has provided an overall genetic map of the Jewish Diasporas. The findings support the historical record of Middle Eastern Jews settling in North Africa during Classical Antiquity, proselytizing and marrying local populations, and, in the process, forming distinct populations that stayed largely intact for more than 2,000 years. The study, led by researchers at Albert Einstein College of Medicine of Yeshiva University, was published...

Gene is linked to so-called 'intersex' families The Y chromosome is supposed to genetically seal a fetus's fate in terms of gender.

Now an international team led by Harry Ostrer, MD, director of the...

A variety of genetic factors are involved in sex determination. If something goes wrong with one of these factors, people who have a chromosome set that predicts they will be of one sex may develop as the other sex or have traits on the spectrum between the two sexes. There can be emotional and social stress associated with disorders of sex determination (DSD), and in many cases, infertility is an additional problem. Several genetic alterations that cause DSDs have been identified, and work...

Using sophisticated genomic analysis, scientists have probed the ancestry of several Jewish and non-Jewish populations and better defined the relatedness of contemporary Jewish people. The research, published by Cell Press in the June issue of the American Journal of Human Genetics, may shed light on the question, first raised more than a century ago, of whether Jews are a race, a religious group or something else. The genetic, cultural and religious traditions of contemporary Jewish people...
