no it is not. d.s. is a trait from your parents gene and if you get one less or more of the natural chromosomes then you are special.
Disorders, such as Down's Syndrome, are caused by nondisjunction.
Nondisjunction
No. Down Syndrome is caused by polyploidy of 21st chromosome (trisomy-2n+1 condition).
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.
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.
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.
Its on top of the trans as you're looking down. Its not internal. I've replaced mine on my 1997 Sable.
down syndrome
Trisomy 21 (Down's syndrome), Turner's syndrome (XO), and Klinefelter's syndrome (XXY) are a few examples of genetic disorders that can result when chromosomes don't separate correctly during meiosis.
Down's syndrome is caused by trisomy of the 21st chromosome. This is mostly caused when the chromosome pair fails to separate properly (nondisjunction).
It will result 4n cells.Chromosomal number will be doubled from generation to generation. It also will result in abnormal individuals that may not to be able to adapt. Down's Syndrome and Turner's Syndrome are examples of this.
Down syndrome is generally the preferred spelling, although Down's syndrome is sometimes used in American sources.
