What else can I help you with?
What is a chromosomal disorder that could result from nondisjunction?
Disorders, such as Down's Syndrome, are caused by nondisjunction.
What was Down syndrome called in 1940?
It was called Down Syndrome back then, too.
Which process could result in the type of cell mutation that causes Down syndrome?
Down's syndrome is caused by trisomy of the 21st chromosome. This is mostly caused when the chromosome pair fails to separate properly (nondisjunction).
Is down's syndrome a result of aneuploidy?
No. Down Syndrome is caused by polyploidy of 21st chromosome (trisomy-2n+1 condition).
Is down syndrome a mutation?
Down Syndrome is caused by extra genetic material on Chromosome 21. About half of the children of people who have Down Syndrome are born with Down Syndrome themselves. See the Related Linksbelow to view an article about the genetics of Down Syndrome.
Is Down syndrome a single gene or polygenic trait?
Down syndrome is a result of having an extra chromosome in one's genes. Chromosome thirteen* if your that much into the science. It is also called trisomy 21 because the chromosome 21 is the one with the abnormalities. *Abnormalities with chromosome thirteen is called Patau syndrome or trisomy 13.
Causes Down Syndrome?
Having an extra copy of chromosome 21. You are supposed to have 2; when you have 3 (trisomy 21), Down's Syndrome is the result.
Is down syndrome a frame shift mutation?
yes, down syndrome is caused by non disjunction, an error in the process of cell division
Is there a prenatal diagnosis or test for Down syndrome?
Yes there are examination that can determine that a fetus has down syndrome.. called amniocentesis.
What is the process by which rocks break down as a result of chemical reactions?
It's called chemical weathering.
If a pregnant woman takes Procardia can this cause her to bear a baby with Down syndrome?
Down syndrome is a genetic defect and is the result of an extra chromosome at the time of conception. The use of Procardia (or any other drug) does not cause Down syndrome.
Why do people call Down Syndrome Down's?
Down syndrome is the correct term. People who are using "Downs" are speaking incorrectly. Down syndrome used to be called Down's syndrome, but since John Langdon Down did not have nor "invent" this chromosomal abnormality, the correct name is Down syndrome. Countries such as the UK, still use the term Down's syndrome, but shortening it to Down's is not using people first language, therefore, it is incorrect.
