Hai everybody why nobody marry his father brothers daughter.....tell me the reason...?

Answer 1

Because your father's brother's daughter is your first cousin. And in many countries, marrying a first cousin is illegal. It's called "incest". The reason is to broaden the gene pool. Your cousin may carry many of the same genes as you, so the likelihood of birth defects is greater if you marry close kin and have children together.

Answer 2

In some places (like the UK) it is legal to marry your cousin, in other places it is viewed as incest as the blood relationship is still fairly close. I would advise sticking to your local custom.

Answer 3

1. Because she is your cousin
2. Because it is illegal.
3. If you were to have children they could be born with serious genetic defects many of which could lead to an early death.
4. eeew.

Answer 4

In the U.S many states (maybe all) consider first cousin marriages too close in bloodlines and have made it illegal.....it's considered almost as close as marriage with your sister..incest, my dear. That's why.

genetically speaking it's unwise..the odds of having a kid with an inherited illness/condition peculiar to any particular family is increased greatly...and one does want healthy children...right?????

Answer 5

That would be your 1st cousin and it is wrong by law and it is medically a bad ideal you will mostr likely have normal children as the blood lines are too close

Answer 6

In Kentucky they do.

Hmm... Interesting I guess in Ky they don't but it is legal in many other states, check this out.
