Down syndrome is a genetic disorder that is typically caused by an extra copy of chromosome 21 in a person's genome. in a small number of cases, however, down syndrome occurs because a section of chromosome 21 becomes fused onto another chromosome. the type of down syndrome that occurs because a section of chromosome 21 attaches to another chromosome is an example of a genetic disorder caused by

The correct answer is chromosome translocation.

Chromosome translocation refers to a chromosome unusualities resulting due to the reorganization of the components between the non-homologous chromosomes. A fusion of gene may be produced when the translocation connects two otherwise-different genes. It is determined on karyotype of affected cells or on cytogenetics.

Down syndrome is a disorder caused in a few of the cases by a Robertsonian translocation of the chromosome 21 long arm onto the long arm of chromosome 14.

i'm pretty sure it's spores
