A trisomy is when a person has 3 versions of a chromosome. 'Normal' humans will only have 2 of each chromosome.
For example, having 3 versions of chromosome 21 is known as Trisomy 21 or Down syndrome.

Trisomy-21 results from a mutation to the chromosomes in?
Gametes
If child is born with trisomy when did the mutation occur?
during meiosis
What are mutation that result in death?
These are called fatal genetic mutations. Same examples are: Tay-Sachs disease, Neimann-Pick disease, Trisomy 18 and Trisomy 13 are "Edwards Syndrome" and "Patau Syndrome," respectively and Cystic fibrosis
When a child has Trisomy when does the mutation occur?
during meiosis
Can Trisomy 18 be detected?
Trisomy 18 can be detected before birth
Trisomy-21 results from a mutation to the chromosomes in?
Gametes
If child is born with trisomy when did the mutation occur?
during meiosis
Trisomy is a mutation that results in a cell having an extra?
A trisomy is a condition in which a person has three copies of a chromosome instead of the usual two copies. A person can have full trisomy (three copies in every cell) or mosaic trisomy (three copies in some cells but not all).
Type of mutation that causes Trisomy 18?
Very sure that it is insertion, because there are three chromosome 18s instead of two.
What are mutation that result in death?
These are called fatal genetic mutations. Same examples are: Tay-Sachs disease, Neimann-Pick disease, Trisomy 18 and Trisomy 13 are "Edwards Syndrome" and "Patau Syndrome," respectively and Cystic fibrosis
What are examples of diseases caused by chromosomal mutation?
Down's Syndrome Kleinfelter's Syndrome
When a child has Trisomy when does the mutation occur?
during meiosis
Is color blindness monosomy or trisomy?
trisomy
Can trisomy 18 be cured?
There is no cure for trisomy 18
What type of condition is trisomy?
Trisomy an abnormality in chromosomal development.
Down syndromeis caused by errors in what?
Downs syndrome is caused by a genetic mutation called trisomy. Trisomy is when an extra chromosome is present on one set of chromosomes, so instead of the 46 chromosomes of a normal human there are 47. Trisomy can often result in miscarriage as the body cannot cope well with extra chromosomes. Downs syndrome is when there is an extra chromosome 21. Other genetic defects which are caused by trisomy are Edwards syndrome and Patau syndrome.
Which process could result in the type of cell mutation that causes Down syndrome?
Down's syndrome is caused by trisomy of the 21st chromosome. This is mostly caused when the chromosome pair fails to separate properly (nondisjunction).
