Pakistan is often cited as having one of the highest rates, with approximately 61–65% of marriages being consanguineous.
What ethnicity has the most inbreeding?
Consanguineous unions range from cousin-cousin to more distant relatedness, and their prevalence varies by culture. Prevalence is highest in Arab countries, followed by India, Japan, Brazil and Israel.
What country is most known for inbreeding?

Where is inbred most common?
Inbreeding, or consanguineous marriage (typically cousin marriages), is most common in parts of the Middle East, North Africa, and West Asia, with rates sometimes exceeding 50% in countries like Pakistan, Saudi Arabia, and Kuwait. It is often tied to cultural traditions, tribal structures, and the desire to keep assets within the family.
What is the most inbred species in the world?
The Devils Hole pupfish (Cyprinodon diabolis) is considered one of the most inbred animal species in the world. A study revealed that 58% of their genomes are identical, a level of inbreeding equivalent to five to six generations of full-sibling matings. These endangered fish live in a single, isolated Nevada cave, keeping their population exceptionally low and genetic diversity to a minimum.

Which race has the most birth defects?
American Indian/Alaska Native infants have the highest overall rate of birth defects in the United States, with a 50% or greater prevalence for several major conditions compared to other groups. While American Indians have the highest rates, other studies show higher prevalence for specific conditions among Hispanic (e.g., Down syndrome) and Black (e.g., severe heart defects) infants.

While not universal, this practice is culturally accepted and often favored in certain regions to keep family ties close, despite the increased risk of genetic disorders.
Is inbreeding common in Japan?
Inbreeding rates in Japan have significantly declined over the past few decades and are currently low, although they were historically high, particularly in rural areas. Consanguineous marriage (cousin marriage) rates dropped from over 20% in the early 1900s to under 1% in many urban areas by the late 20th century, making inbreeding uncommon today.
What is the inbreeding rate in Gaza?
The Sirdah study of 156,635 people observed that in Gaza, the frequency of consanguineous marriages is significantly higher in semi-urban areas (41.6%) than in urban (39.1%) (P<0.001) (34).
Which cultures have inbreeding?
The practice of marriages between close relatives (typically cousins) is known as consanguineous marriage. Although rare in the Americas and modern Europe, consanguineous marriage is notably common in North Africa and the Middle East, where it is a traditional and respected aspect of many Arab and Muslim cultures.
