An uncle and his niece, or an aunt and her nephew a second-degree relationship share a quarter of their genes. Through a combination of old prejudices and present-day conventional wisdom about inherited birth defects, first cousin marriage is seen by many as a little too close for comfort, as well as a bad idea if you want children. You'd think Darwin of all people would know better. This was a few years ago so I don't remember the numbers but it's more common than you think. The most likely reason, scientists say: offspring of such close relatives were likely to have much shorter life spans, because of the chance of inheriting harmful genetic mutations.
If there are dangerous dominant traits in both main branches of the family, then it isn't. Any offspring might have a rough time at school though. For your reference, this increase in birth defect rate is about the same as the increased risk of a woman having a baby when she is 40 vs. This is because each person carries a gene change and has a 50% chance of passing down this change to their child. And for all you blue eyed people: Your genetic mutation blue-eyes could possibly mean that you are inbred and related to everyone else who has blue eyes.

Then Albert married his own first cousin. They were noble lords who were the byproduct of generational inbreeding, as a result they became anemic, had facial deformities and some were actually allergic to sunlight. Some geneticists believe that everybody on Earth is at least 50th cousin to everybody else. This error is very easy to avoid. Franklin Delano Roosevelt and Eleanor Roosevelt were fifth cousins, once removed a chart showing their relationship is available at. They passed down those strong genes associated with survival, unlike the houses of Europe that intermarried and passed down hemophilia. The researchers, a panel convened by the National Society of Genetic Counselors, based their conclusions on a review of six major studies conducted from 1965 to August 2000, involving many thousands of births.
An interesting side issue is called pedigree collapse. People are getting this information from small-town doctors who may not know the risk, don't have access to this information and just assume it's a big risk. Thus lowering the possibly of siblings marrying each-other if say you wanted to marry your cousin but you could actually be marrying a half-sister.

No genetic relationship at all. Still it does happen of course. Even though longstanding ones reflect a view that such marriages are ''really bad,'' he said, ''the data show it isn't that bad. Then, after just two weeks, Grace and Dylan run out of money and must go back home to Tennessee, where they are still being shunned by their family.

What did Queen Victoria, Charles Darwin, and Albert Einstein have in common? For ten years, he lived a miserable existence. However, some couples may share no recessive traits, and would therefore have no increased risk. After all, can you name all your third cousins and fourth cousins and those even further away in the family tree? Especially putting bail money up for the dude. And for all of the people who think that having kids with a cousin will create crazy deformed mutants, its not true. This needs to be taken into account when examining the data.
Monozygotic identical twins have the same genetic make-up and share 100% of their genes. And for all the Creationists out there: God put Adam and Eve on this earth.
