This is known as a trisomy. So if there are 3 of chromosome number 13, you would call it trisomy 13.

The presence of three copies of a particular chromosome is known as trisomy. This genetic condition can lead to developmental abnormalities, such as Down syndrome which is caused by trisomy of chromosome 21.

What is it called when an individual has three copies of a chromosome?
Having three copies of a chromosome is known as trisomy. This genetic condition can lead to developmental abnormalities and is commonly seen in disorders such as Down syndrome (trisomy 21).
A segment of chromosome responsible for a particular characteristic?
DNA or genens these are the segments of the chromosome.
The human gene associated with color vision are located on the what chromosome?
The human genes associated with color vision are located on the X chromosome. Specifically, the genes for three types of color receptors (cones) - blue, green, and red - are located on the X chromosome. This is why color blindness, which is more common in men, is often linked to mutations in these genes due to their presence on the X chromosome.
What are the major chromosomal changes in trisomy?
Trisomy is defined as the presence of three homologous chromosomes. For example, Down's Syndrome is caused by trisomy-21, 3 copies of chromosome 21.
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.

What common condition is caused by presence of three copied of chromosome 21?
Down syndrome
What is trisomy syndrome?
In a trisomy syndrome, an extra chromosome is present so that the individual has three of a particular chromosome instead of the normal pair.
What does the karyotype of a person with down syndrome show?
A genetic disorder caused by the presence of all or part of a third copy of chromosome 21.
What determines the sex of an individual?
Presence or absence of the Y chromosome
A segment of chromosome responsible for a particular characteristic?
DNA or genens these are the segments of the chromosome.
What type of mutation causes Edwards' syndrome?
An extra copy of Chromosome 18

What single attribute determines that a human fetus is male?
The presence of a Y chromosome.
What does a person with an X chromosome and a Y chromosome have?
A person with an X and Y chromosome typically identifies as male. The presence of the Y chromosome determines male sex development, leading to the development of male characteristics during puberty.
