Chromosomal mutations can have a variety of effects on individuals. down syndrome is a disorder that causes problems such as mild to moderate mental retarationn and slow or stunted development. a common form of this disorder is the result of a genetic mutation that occurs when there is an extra chromosome 21. which type of chromosomal mutation causes this form of down syndrome? nondisjunction inversion deletion insertion

The correct answer is nondisjunction.

Explanation:

The nondisjunction of the chromosome can be defined as the failure of separation of sister chromatid during meiosis. Due to the nondisjunction during the cell division, one daughter cells gets two chromosome and other daughter cell gets none of it. In case, the daughter cell having two chromosome is fertilized by a normal gamete it can result in trisomy.

In the case of Down Syndrome, the nondisjuction of the chromosome number 21 takes place.
