first cousins CANNOT have the same DNA.
siblings share 50% of their DNA, and first cousins share 25%. I'm not sure which test you are refering to, as 99.9% DNA match would infer identical twins.

What does cousin mean?
http://www.urbandictionary.com/define.php?term=kissing+cousinA "kissing cousin" is any cousin that is not a first cousin. In most places in the world, first cousins may not have sex and have babies. But, in most cultures second cousins, and higher can have sex and babies. Degree of cousinship is determined by how many generations the shared ancestor is removed from the individual closest to the generation of the shared ancestor.If we share the same grandparent we are first cousins, and therefore should avoid physical encounters with each other which might lead to sex. First cousins are NOT "kissing cousins." If we share the same great grandparent we are second cousins and are therefore able to kiss and do whatever we want, including having sex, and have babies together.by Fredric Roe July 08, 2006

Your fiance is in your first cousins will there be any problems in your married life in future?
In case this is a real question, I am told that its not legal to marry your first cousin and that any child resulting from two first cousins would have a considerably higher chance of birth defects. I believe second cousins are alright though, legally
Can first cousins have same DNA if child is tested with one cousin and test comes back 99.60 is it possible that the other cousin can test higher than that or be more accurate than 99.60?
Not very likely the other will test as high because the two cosins are from two different parents with two totally different DNAs. Only one that might come close to matching a test is an identical twin. I wold say cousin number 1 is the parent!
Are you an uncle to your first cousin's child?
Of course you are related to the child of your parent's first cousin, second cousin or fifteenth cousin. You are related because at some point back in history the two of you have an ancestor in common. It may be your grandparent, or it may be a great great great... grand parent. But if you can show a common ancestor, you are related to each other. With higher numbers, the relationship becomes more and more tenuous.Your parent's first cousin is your first cousin, once removed. A child of your parent's first cousin is your second cousin.
What does "once removed" actually mean?
The term "removed" refers to the number of generations separating the cousins themselves. So your first cousin once removed is the child (or parent) of your first cousin. Your second cousin once removed is the child (or parent) of your second cousin. And your first cousin twice removed is the grandchild (or grandparent) of your first cousin.
Are there birth defects from first cousins?
Usually, first cousins who have children together will have perfectly healthy children, without birth defects. However, the chances of a problem are increased for first cousins compared to the chances for less closely related parents.
Are half cousins cousins?
AnswerThey are "half-cousins" as the name clearly points out, not full cousins. Yes, they are cousins, though. AnswerThere is no such thing as a "half-cousin," a modern term constructed to parallel "half-brother" and "half-sister." A half-sibling is a person who shares one but not both parents with you.A cousin is a person who is not a sibling but shares one or more ancestors with you. Your first cousin may be the child of your uncle, and therefore shares at least one grandparent with you. Whether your uncle is the full brother or the half-brother of your parent makes no difference. He is still your uncle and his children are your first cousins.
Does Italian Law permit me to marry my first cousin once removed and is it safe to have children in this marriage?
In a lot of countries around the world is it legal to marry your first cousin. Checking with the local licensing office is the best way to find out if you will be violating any laws. Children born of cousins do have a slightly higher risk for genetic disorders.
Are first cousins three times removed still related to you?
Anyone who is correctly designated as your first cousin, second cousin, etc, no matter how many times removed, is still related to you. The more times removed they are, or the higher number of cousin they are (second cousin, fifth cousin, eleventh cousin, etc), the more distant is that relationship.
Can your son marry your first cousin?
First of all, it's a bit odd that someone would actually want to do this, so I'm hoping it's one of those situations where you didn't realize you were cousins, next how old are you? At first you saying the cousin is six year younger seemed insignificant but if someone is 18 looking at a 12 year old it is very significant. Having that out of the way, I want to clear up what the person before me wrote. I work with individuals who have disabilities (the term mental retardation isn't used anymore), first cousins who have children have a SLIGHTLY higher chance of having a child with a disability, however that should not stop you from having children, it's more likely for a woman over 35 to have a child born with down syndrome, than it is for cousins to have a child with a disability. you can marry legally. but there will be a higher chance of abnormalities, even mental retardation if you decide to have children. It depends on the laws in your state and if both are of legal age.
What birth defects will your baby have if you have it with your first cousin?
None in a majority of cases. There is little evidence that marriage of first cousins once in a while in a family line is not likely to be an issue. It is not illegal to marry a first cousin in many states.
