If someone has an extra chromosome it means there was a genetic mutation that is abnormal in human development. It may result in problems with the person affecting them on a basic level, or may go fully unnoticed. A common disorder that can be caused by having an extra chromosome is Down's Syndrome.
The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.
No, not all cases of Down syndrome involve a complete extra chromosome. The most common form, known as trisomy 21, consists of an entire extra chromosome 21, resulting in three copies instead of the usual two. However, some cases are due to a Robertsonian translocation, where a part of chromosome 21 is attached to another chromosome, or mosaic Down syndrome, where some cells have the extra chromosome while others do not.
An abnormal number of chromosomes is called aneuploidy. If a chromosome has 3 of its kind, it is trisomic. The exact condition depends on which gene has the extra chromosome.
You might see an extra chromosome or a missing chromosome. You might see a piece of a chromosome missing, or a piece added onto another chromosome.
An extra chromosome can cause genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21. This leads to developmental delays, intellectual disabilities, and certain physical characteristics.
This is a birth defect. A person born with this has an extra chromosome 21.
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
Aneuploid - the individual has an extra copy of one chromosome or is missing a chromosome.
A diploid cell with an extra chromosome. Basically a diploid with an extra chromosome of one type, producing a chromosome number of the form 2n + l.
no
Down syndrome occurs because of the extra chromosome on chromosome 21. If you go onto google images and type in karyotype of Down syndrome, you will find a picture of the extra chromosome. Instead of having two chromosomes on chromosome 21, there is an extra. Type your answer here...
An extra copy of Chromosome 18
In females, the extra X chromosome becomes inactive and becomes the Barr body.

The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.
Down Syndrome is when there is an extra chromosome in someones DNA. More exactly it is when the 21st chromosome has an extra one.
