ANSWER.
* Edward syndrome is a trisomy chromosomal disorder characterized by
presence of an extra copy of chromosome 18.
* Total number of chromosome in a normal person is 46.
* So a person with Edward syndrome have 47 chromosomes.
* Other examples of 47 chromosome disorders are down syndrome and
Palau syndrome.
