Yes, it's result of an extra chromosome in 21, which is why it's often referred to as trisomy 21.

What is an extra set of chromosome?
The condition in which an organism has complete extra sets of chromosomes is called polyploidy. This condition can cause a number of severe birth defects. Most do not live a full lifespan for their species.
What is a chromosomal disorder that could result from nondisjunction?
Disorders, such as Down's Syndrome, are caused by nondisjunction.
Whether each and every human cell posses 46 chromosomes?
no, normally humans do have 46, but certain mutations or genetic disorders can result in more, less, or fused chromosomes. the most common example of missing chromosomes is down's syndrome. when someone has an extra chromosome(s) it's called polyploidy. i can't tell you too much about fused chromosomes.
What will happen if sex cells carry diploid chromosomes?
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.
What types of organisms are polyploidy?
Polyploidy occurs in cells and organisms when there are more than two homologous sets of chromosomes. "occurrence of polyploidy suggests an evolutionary advantage of having multiple sets of genetic material for adaptive evolution"
Is down's syndrome a result of aneuploidy?
No. Down Syndrome is caused by polyploidy of 21st chromosome (trisomy-2n+1 condition).
What is an extra set of chromosome?
The condition in which an organism has complete extra sets of chromosomes is called polyploidy. This condition can cause a number of severe birth defects. Most do not live a full lifespan for their species.
What is a chromosomal disorder that could result from nondisjunction?
Disorders, such as Down's Syndrome, are caused by nondisjunction.
Which one is not a genetic disorder color blindness hemophilia cystic fibrosis down syndrome?
Down syndrome is a polyploidy (three chromosome 21s)and is considered to be a somatic disorder. The other three are genetic because they are present in the form of a defective allele on achromosome.
The process that result in Down syndrome is called?
Nondisjunction
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.
What is 48xxyy?
48,XXYY syndrome is a sex chromosome anomaly in which males have an extra X and Y chromosome. AKA Polyploidy
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.
The condition in which a diploid cell has an extra chromosome is called?
Polyploidy is the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
Is a kiwifruit a polyploidy?
Yes, kiwi fruit is a polyploidy.

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.
