"Family blood relation" isn't really a scientific concept. If you think about genes, though, you and your siblings have, on average, half of your genes the same and half different. First cousins have 1/4 of your genes in common, and 3/4 different. Second cousins would share 1/8, third cousins 1/16, fourth cousins 1/32 and so on. (Remember that these numbers are statistical averages, not absolute fractions.) So, if humans have about 32,000 genes (there are a few more, but 32,000 will make the numbers easier to deal with), then you and your 4th cousins still have (on average) about 1000 genes the same. 5th cousins would share about 500 genes, 6th cousins about 250 and so on. You'd have to go to like 14th or 15th cousins before the odds are that you don't share any genes with each other.

In ny? it extremely is criminal. And if he's your 4th or fifth then it might want to be criminal quite plenty everywhere - d*mn you're between the fortunate ones! I fell for my First Cousin, as right now as bumped off and that i stay in TX - the position it extremely is illegitimate. Deformities... You men might want to have as plenty probability for that as each and every person else available! 4th cousins are as heavily proper as strangers, so that you'll possibly want to no longer have some thing to pressure about. In ny, with a 4th cousin - confident you may want to marry your cousin. EDIT: a million.7% is the more effective volume for deformities for First Cousins, by ability of ways. 2d cousins have not were given any improve. so that you have not some thing to pressure about. and human beings are such morons about those jokes proper to the South - questioning it extremely is criminal in additional effective Northern states it truly is!

I'm not sure. However, if you are so disposed, the Levitical code offers some insight in the area of marriages at a time when it was critical. Some research in that direction may yield some results. Hope this helps.

I believe it's not a good idea for first cousins to have children because of the lack of variety in their genetic codes. But after that I'm not sure.

Depending on context, a chimp is a cousin.
So it never fully dilutes Everything alive on Earth is related.

Depends on culture. Indians, Chinese, Italians have large family ties.
