How do you get barth syndrome?
Barth's Syndrome is not something you get from a virus or a bacteria. It is genetic, on the X chromozome. It means that a women is mostly only a carrier, and when a carrier woman marries a amn, 50% of their boys will have Barth's Syndrome and 50% of their girls will be carriers. All the other boys and girls will be healthy. Have good health, firstname.lastname@example.org
Asked in Down Syndrome
Is Down syndrome hereditary?
The majority of Down syndrome cases are not hereditary. Only in cases of Translocation Down syndrome is this then possible. These inherited cases then occur because one of the parents is a carrier. A carrier will have 45 chromosomes instead of 46 but they will have all the genetic material of a person with 46 chromosomes. Remember that in Translocation Down syndrome the extra chromosome 21 material is located on a different chromosome. A carrier will have the extra material but will have only one chromosome 21. The carrier will not exhibit any of the symptoms of Down syndrome because they have the correct amount of genetic material. However, a carrier will have an increased chance of having a child with Down syndrome. If the carrier is the mother, the chances are approximately one in five of having a child with Translocation Down syndrome, but if the carrier is the father, the odds are 1 in between 20 and 50. In cases where the carrier has no unattached chromosome 21, all the carriers' children will have Down syndrome. The ability to have children varies among people with Down syndrome (generally they have a reduced rate of fertility). Down syndrome is also known as trisomy 21 and happens when you have three chromosomes instead of two on the 21st 'pair.' This happens when there is an error in cell division and instead of 46 chromosomes dividing into two new cells with 23 each, one of the new cells will have 24 (and therefore the extra '21' chromosome). So it's not really a hereditary thing -- the chances of giving birth to a child with Down syndrome increases after the age of 35 or so, and in general the odds are 1 in 800 of having a child with Down syndrome. It is mostly caused by an accident of gene formation. A small percent is hereditary. It is a genetic abnormality, but not inherited, per se.

What are the possible genotypes of the parents if the abnormality describe the abnormality for fragile X syndrome?
A/X X/A NIKKI SMITH **** Less than 1% of Fragile X Syndrome cases are a result of deletion, neither parent is a carrier. If a father is the carrier/full mutation, XY, he will pass the mutated gene to all of his daughters, all of his daughters will be carriers. If the mother is the carrier/full mutation, xX, with each pregnancy she has the possiblity of passing on fragile X as a pre-mutation (carriers) or full-Mutation to every child (male/female).

Asked in Insurance
What is the third party carrier?
when an insurance company(x) does not have particular coverage(ex:Earthquake coverage) then they would cover those coverages with the help of another insurance company(Y) by paying a certain percentage of premium to that company(third party carrier) and provides that coverage to their customers. Here Y becomes a third party carrier
What causes Moebius syndrome?
Moebius syndrome is felt to be a genetically inherited condition, as a parents' state of health (other than being a genetic carrier) and environmental or external factors do not seem to play a role in its occurrence. Genetic counselling is felt to provide the best preventive therapy against its appearance, since surgery and physical and speech therapy are the only modalities for treatment after birth with this rare syndrome.
Is Edward's syndrome caused by a recessive gene?
Edward's syndrome is not technically recessive or dominant, because it is not caused by a single gene. Rather it happens due to a trisomy of chromosome 18 (or just of a part of said chromosome). Parent's may be healthy and still have offspring with the syndrome not because its recessive, but because the trisomy arises during meiosis of the gametes. Whatever happens to the gametes affects only the offspring not the carrier parent.

Is carrier signal present at output of double side band suppressed carrier?
No, the carrier signal is not present at the output of double side band suppressed carrier. That is what suppressed carrier means. However, the receiver has enough information to regenerate the carrier if need be. The advantage of suppressed carrier mode is that more power can be deployed to the signal-carrying portion of the modulated carrier.
