Actually Yes you would
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
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.
PG-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.
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.
Chromosome
8 and 13
Either chromosome 13 or 7. Mostly 13
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
