What is the punnett square for down syndrome?
This question has been improved by another user: actually, this is both a genetic disorder and a chromosomal disorder. It is a genetic disorder because this disorder is often transmitted from one (or both) of the parents to their young. It is possible to make a punnett square, however there is a better way to do this, which is why you probably will not find a punnett square of this disease online. The better way is by using a karyotype.
