No Gay Gene Says Eight Major Studies of Thousands of Twins in Three Different Countries
In a report posted by Dr. Neil Whitehead at Pastor Holland Davis's website and many other pro-family or Christian websites it is reported that there is no scientific evidence that "homosexuals are born that way".
Whitehead reveals "Eight major studies of identical twins in Australia, the U.S., and Scandinavia during the last two decades all arrive at the same conclusion: gays were not born that way. "
(The studies included "twin registers" containing from 25,000 to 600,000 persons in the respective countries)
"At best genetics is a minor factor," says Dr. Neil Whitehead, PhD. Whitehead worked for the New Zealand government as a scientific researcher for 24 years, then spent four years working for the United Nations and International Atomic Energy Agency. Most recently, he serves as a consultant to Japanese universities about the effects of radiation exposure. His PhD is in biochemistry and statistics.
Identical twins have the same genes or DNA. They are nurtured in equal prenatal conditions. If homosexuality is caused by genetics or prenatal conditions and one twin is gay, the co-twin should also be gay.
"Because they have identical DNA, it ought to be 100%," Dr. Whitehead notes. But the studies reveal something else. "If an identical twin has same-sex attraction the chances the co-twin has it are only about 11% for men and 14% for women."
Because identical twins are always genetically identical, homosexuality cannot be genetically dictated. "No-one is born gay," he notes. "The predominant things that create homosexuality in one identical twin and not in the other have to be post-birth factors."
