The severity of the condition and the associated signs and symptoms vary based on the size and location of the duplication and which genes are involved.

WebThough it looks like there are two of each chromosome in each cell, these are duplicated chromosomes; ie, it is one chromosome which has been copied, so there is only one possible allele in the cell (just two copies of it).
