An individual with an extra copy of chromosome 21 has Down syndrome, a genetic condition that typically results in distinct physical traits such as a flat facial profile, almond-shaped eyes, and a short neck. They may also experience developmental delays, varying degrees of intellectual disability, and have a higher likelihood of certain health issues, such as heart defects. Despite these challenges, individuals with Down syndrome can lead fulfilling lives and often exhibit unique strengths and talents. Early intervention and supportive therapies can greatly enhance their development and quality of life.

Which refers to the addition of an extra segment of a chromosome?
This is known as a chromosomal duplication, which involves the replication of a segment of a chromosome resulting in an extra copy. Duplication can lead to genetic disorders or variations in an individual's traits.
How does trisomy occur?
Trisomy occurs when an individual has three copies of a particular chromosome instead of the usual two. This can happen during the formation of sperm or egg cells, leading to an extra copy of the chromosome in the resulting embryo. Trisomy can result in conditions like Down syndrome, where there is an extra copy of chromosome 21.
An individual with an extra copy of chromosome 21 demonstrates traits collectively know as?
Down syndrome. This condition is characterized by developmental delays, distinct facial features, and potential health issues such as heart defects and cognitive impairment.
What chromosomal mutation causes an extra copy of chromosome 13?
Trisomy 13, also known as Patau syndrome, is a chromosomal mutation where there is an extra copy of chromosome 13 in each cell. This condition can lead to various physical and intellectual disabilities.
What does it mean when someone has an extra chromosome?
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.
What does an individual with an extra copy of chromosome 21 demonstrait traits of having?

What is the condition in which an individual has three copies of a chromosome?
The condition in which an individual has three copies of a chromosome is called trisomy. It can result in genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21.

What type of mutation causes Edwards' syndrome?
An extra copy of Chromosome 18
Do people with Down Syndrome have 47 genes?
People with Down syndrome typically have 47 chromosomes, not genes. This extra chromosome is usually a third copy of chromosome 21, leading to the condition often being referred to as trisomy 21. The presence of this extra chromosome affects various physical and intellectual traits associated with Down syndrome.
What is Edwards' syndrome?
Edwards' syndrome is caused by an extra copy of chromosome 18
