Geneticists now say that it's OK to marry first cousins, but the jury really is out on this one, and there are times when there can be something wrong with offspring. It's best to talk to your family doctor about this one or go on: www.Google.com TYPE IN: Can first cousins have children? You really need to look this up and decide from there. Many people feel it's odd one would marry a cousin, but it happens quite often. There are times you may not see that cousin all that much and fall in love when you do finally meet, or if cousins are close they can be best friends for years and fall in love with each other. Some states do not allow first cousins to marry, so you need to check the laws in the appropriate places before applying for a license. Scientists say that 5% of DNA in each human body is made up of "disease genes," or genes that will predispose or cause disease. Luckily, this DNA is usually found in a recessive allele and so does not cause any harm. Incestry can be dangerous because closely related people often have the same disease genes, causing their offspring to be born with both copies of the recessive allele.

∙ 14y agoMany (most) second cousins who marry have perfectly healthy children. Second cousins are more closely related to each other than most married couples are. This means that their chances of having a child with some genetic disease related to a recessive gene is greater than if they were not so closely related.

Should genetic research involving cloning be practiced in this country?
genetic research generally involves cloning, as in cloning unicellular organisms and some animals but cloning humans is not allowed and should not be allowed. in a nut shell genetic research involving cloning should not be practiced in any country because a lot of people disabuse opportunities given to them.
Why might parents decide to have genetic testing?
Parents might decide to have genetic testing to determine if either or both of them carry certain genetic traits that could be passed on to their offspring. Some genetic traits will lead to severe birth defects or problematic diseases that could severely impact the quality of their children's lives. If they are indeed carriers of certain traits, they may choose to avoid having children or choose adoption as an alternative. In this way, they can eliminate their particular genetic line and avoid passing the trait on to the next generation.
Why is it difficult to cure a human genetic disorder?
It would require changing a person's genes. We can't do that. Yet. Until we do, the genes that gave you the disease will get passed to your children, and THEIR children, etc.
What is the most common symptom of a genetic disorder?
The most common symptom of a genetic disorder is the abnormality in chromosome structure or number. People with a genetic disorder have a distinct physical or facial feature like abnormally shaped ears.
Can a person with a genetic disorder that has been corrected by gene transfer pass the corrected condition to his or her children?
No, because their genes will be changed.
Are you second cousins once removed?
if second cousins once removed have children together, will the children have genetic problems
What happens when you have a baby with a relative?
It depends on how close a relative. It is legal to marry and have children with cousins however anyone closer related it is illegal to marry or have children and the children will potentially have genetic problems
Is it safe to marry cousins?
No, the children may have genetic defects.
Can two cousins have a baby and is anything going to go wrong with the baby?
It will depend on the laws in your jurisdiction. There are many places where first cousins can legally marry. Some that allow that will only do so if they cannot have children. Others will allow them to have children and don't believe there will be an issue with any genetic problems.
Why first cousins but not second cousins can marry?
First cousins can marry in many places because they are considered to have a close enough blood relationship that potential genetic risks or abnormalities can be assessed before marriage. However, second cousins have a more distant blood relationship, and the risk of genetic disorders decreases significantly, which is why they are generally allowed to marry.
Should parents with genetic disorders be allowed to have children?
i see no problem with it. i see no problem with it.
What are people who like their cousins called?
inbreeding= the act of of mating genetically within the same genetic pool (close relations) Mating with 1st cousins does contribute to inbreeding and can be OK but often presents genetic problems, which is far less likely with 2nd cousins to the point where it is basically OK to marry a 2nd cousin. Some 1st cousins can and do marry and everything is fine, especially with genetic testing prior to having kids. In many small towns throughout history cousins tended to end up married here and there- the worst problems come from repeated marrying of 1st cousins over and over within a small community or family. This has affected royal families since they could only marry other royals- at times anemia, retardation, and genetic diseases have plagued royal families until they realized the need to bring in some new blood.
Can second cousins have normal kids?
There's every likelihood that the children of first cousins will be "normal" but there is a somewhat increased risk that the children of two such close family members might have a genetic disease or birth defect. The increase in that risk is not huge unless the two first cousins are at the end of a long line of first and second cousin marriages.
Does a first cousin have a close genetic relationship?
No. First cousin share 1/8 of your variable genes and only 1/32 with second cousins. With third cousins you share only 1/128.
Can you have a healthy child after marrying your cousin?
Yes. The risks are overrated. Genetic defects create problems if the families have been intermarrying for many generations. One single generation of cousins marrying don't have a high risk of genetic defects. Many Muslim communities marry their first cousins. Because they have been doing so for many generations, they are at higher risks for genetic disorders. The Royal families of Europe have been intermarrying for generations. That creates risks. But a one off case of cousins marrying and having kids is not high on the risk charts. The social rules that frown on cousins marrying are to avoid genetic disorders if the trend went on for many generations. Not so for a single generation.
Are the genetic makeup the same for first cousins and siblings?
No. Except for identical twins, the genetic makeup of each person is different. However, the more closely related you are to someone, the more similar your genetic makeup. So the genetics of siblings is more similar than of first cousins.
