What is trisomy mutation?
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.
What sex would a person with trisomy X be - Explain?
Trisomy X aka "Triple X syndrome" is a disorder that affects females and is characterized by the presence of an additional X chromosome. Normally, females have two X chromosomes; however, females with trisomy X carry three X chromosomes in the nuclei of body cells. To be male requires a Y chomosome - which those with Trisomy X obviously lack.Trisomy refers to having an extra chromosome - 3 (tri-) instead of 2.Other types of gender related trisomy include:XXY Trisomy (Klinefelter syndrome) where males have an extra X chromosomeXYY Trisomy (or simply XYY karotype) is where males have an extra Y chromosome.
What effect does trisomy-21 have?
By having three chromosomes of the 21 type more protein product is made and the Down's syndrome is expressed.
Which chromosomes are effected in trisomy 13?
Patau syndrome is the result of trisomy 13. Trisomy 13 is usually caused by having an extra chromosome in every cell in the body. Every cell in the human body should contain two chromosomes, one from each parent, however every one in sixteen thousand newborn has three chromosomes. The result of a third chromosome can mean physical disabilities. Most children die within a few days after birth. The disease is not inherited.
Why is it that a mongoloid person have 65 chromosomes?
People with Down syndrome, also called mongoloidism have 47 chromosomes. Having 65 chromosomes would be lethal, as normally having 47 chromosomes is lethal. Down syndrome is also known as trisomy 21, because instead of two copies of chromosome 21, a person with Down syndrome has three copies, which accounts for the 47th chromosome.
What is the genetic disorder for having three 21 chromosomes?
down syndrome

What is the disorder caused by having an abnormality on chromosome 21?
Down's Syndrome or trisomy 21.

Down syndrome is caused by having an extra copy of what chromosomes?
21, the condition is also referred to as trisomy 21.
Which of the following are example(s) of trisomy---Turner Syndrome Down's Syndrome or Klinefelter's Syndrome?
Trisomy means having three copies of a chromosomes. Turner's syndrome is NOT an example of trisomy. Someone with Turner's syndrome has only one X chromosome. Down's syndrome IS an example of trisomy. Someone with Down's syndrome has 3 copies of chromosome 21. Klinefelter's syndrome is a tricky one. On one hand, it would be considered trisomy because they have 3 sex chromosomes. However, they are not all the SAME sex chromosomes. Someone with Klinefelter's has 2 X chromosomes and one Y chromosome.
What effect does trisomy-21 have?
By having three chromosomes of the 21 type more protein product is made and the Down's syndrome is expressed.
On what chromosomes can you find the genetic disorder called Down Syndrome?
Trisomy 21 is the scientific name for the cause of Down Syndrome. Triplication of the 21st chromosome occurs giving it 3 chromosomes total. This is caused when disjunction (splitting) of the chromosome during meiosis does not occur and leaves one cell with 22 chromosomes and the other with 24. When a cell with an abnormal # of chromosomes (24) merges with one having the normal # (23), the resulting fertilized egg has (3) 21st chromosomes or a total of 47.
Which chromosomes are effected in trisomy 13?
Patau syndrome is the result of trisomy 13. Trisomy 13 is usually caused by having an extra chromosome in every cell in the body. Every cell in the human body should contain two chromosomes, one from each parent, however every one in sixteen thousand newborn has three chromosomes. The result of a third chromosome can mean physical disabilities. Most children die within a few days after birth. The disease is not inherited.
What is a genetic disorder that can be detected by karyotyping?
Down's syndrome is one that can be detected, in this disorder the person has one extra chromosome. This chromosome failed to separate during cell divisoin which resulted in a gamete having 24 chromosomes instead of 23. A person with downs syndrome has 47 chromosomes which can be observed by karyotyping.Another in turner's syndrom, in only occurs on the X chromosome and it results in a female missing or having an abnormal X chromosome. In karyotyping you will see that the female only has one X chromosome. It can not occur in males because they only have one X chromosome and a Y chromosome can not survive by it self.Klinefelter's Syndrome is when a male has an extra X chromosome. So he will have XXY (47 chromosomes) this is also detected in karyotyping.Karyotyping is a test to examine chromosomes in a sample of cells, which can help identify genetic problems. They can also be used to study chromosomal aberrations, cellular function, and gather information past evolutionary events.
Why is it that a mongoloid person have 65 chromosomes?
People with Down syndrome, also called mongoloidism have 47 chromosomes. Having 65 chromosomes would be lethal, as normally having 47 chromosomes is lethal. Down syndrome is also known as trisomy 21, because instead of two copies of chromosome 21, a person with Down syndrome has three copies, which accounts for the 47th chromosome.
What type of disorder is klinefelters syndrome gene or chromosomal?
Chromosomal, because the person with Klinefelter's would have 47 chromosomes. A genetic disorder would be any disorder having to do with genes, but would not necessarily mean having an extra chromosome.
