Contrary to widely held beliefs and longstanding taboos in America, first cousins can have children together without a great risk of birth defects or genetic disease, scientists are reporting today. They say there is no biological reason to discourage cousins from marrying. First cousins are somewhat more likely than unrelated parents to have a child with a serious birth defect, mental retardation or genetic disease, but their increased risk is nowhere near as large as most people think, the scientists said. In the general population, the risk that a child will be born with a serious problem like spina bifida or cystic fibrosis is 3 percent to 4 percent; to that background risk, first cousins must add another 1. Although the increase represents a near doubling of the risk, the result is still not considered large enough to discourage cousins from having children, said Dr. Arno Motulsky, a professor emeritus of medicine and genome sciences at the University of Washington, and the senior author of the report. Motulsky said. Even at its worst, 7 percent, he said, ”93 percent of the time, nothing is going to happen. The report is in today’s issue of The Journal of Genetic Counseling.

The mathematics of your next family reunion
I don’t even know how you would find your 4th cousin or whatever. Genetically speaking, a fourth cousin isn’t really a true BLOOD relative, so in that sense it isn’t wrong at all, but I have seen first hand the problems associated with relatives dating and marrying eachother, even if they are distant. My grandfather left my grandmother. If this wasn’t enough drama, he also left her for his distant cousin. The problem with that is that we’re italian and since italian families are so close, my grandfather had grown up around his cousin whom he eventually married then divorced because of their issues concerning being relatives.
Thank you for signing up. Sorry, it looks like an error occurred. Across Australia, cousins are having relationships, marrying and having children together. Kirstie was nine when she first spotted Lyle, 13, at a wedding. A few years later, the pair bumped into each other at a funeral, and when sparks flew, they decided to stay in contact. Although the teenagers were strongly attracted to each other, the couple did everything they could to hide their blossoming romance.
Kirstie and Lyle knew their family might not accept them. After all, they were first cousins. I was just like yeah, whatever, I’ll go with it. She likes me, I like her, sounds good. It wasn’t until Lyle’s mother approved the relationship – and told them it was legal – that the pair decided to go public. When they eventually revealed their secret, the family was shocked. Kirstie and Lyle now have two healthy children together, but friends and family still find it hard to accept their relationship.

He knew that he was adopted, and that he was Irish-American. He never questioned either of those facts until a conversation with his adoptive mother about a decade ago raised some questions.

This post originally appeared on Wait But Why. I learned more than I had ever known about her childhood. I knew she and my grandfather had grown up during the Great Depression, but I never really knew the unbelievable details—things like her seeing a mother and her children being thrown onto the sidewalk by their landlord and left there to starve and freeze until every neighbor on the block chipped in a coin or two from their own impoverished situation so the woman could rent a room for one more month.
I learned a ton about my four paternal great-grandparents—again, I had known the basic info about them, but it was the details that for the first time made them real people.

By Emily Chambers Miscellaneous January 25, Who is this Dolly Harling from Smithtown, and why is she so badass?

I mean, I understand that from a social perspective, sure, you could identify a person who is somehow vaguely related to you. I mean from a present day realistic and genetic standpoint, usually your third cousin is a stranger. If someone is your third cousin, it means your grandparents were cousins.
Or, put another way, your great-grandparents were siblings. Or, to make it blunt, you and your date have a great-great-grandparent in common. Did you feel squicked out? And while time itself does not dilute the gene-pool, basic mating does. You and your third-cousin-lover share less than 1 percentage of your DNA. You need it to be a cool 0 percent? Never hook up with your friends then.

In my article two weeks ago about the odds of knowing a cousin I puzzled over the question of how many 3rd cousins a person might have. This is hard to answer, because it depends on figuring out how many successful offspring per generation the various levels of your family and related families have. Successful means that they also create a tree of descendants. This number varies a lot among families, it varies a lot among regions and it has varied a great deal over time. An Icelandic study found a number of around 2.
