How do chromosomes duplicate
WebThe chance of it happening is a function of the degree of sharing of repetitive elements between two chromosomes. The products of this recombination are a duplication at the site of the exchange and a reciprocal deletion. Ectopic recombination is typically mediated by sequence similarity at the duplicate breakpoints, which form direct repeats.

WebSummary. Chromosome 17p duplication is a chromosome abnormality that occurs when there is an extra copy of genetic material on the short arm (p) of chromosome 17. The severity of the condition and the signs and symptoms depend on the size and location of the duplication and which genes are involved. Features that often occur in people with ... WebChromosome 15q duplication is a chromosome abnormality that occurs when an extra (duplicate) copy of the genetic material located on the long arm (q) of chromosome 15 is present in each cell. 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). The second meiotic division is where sister (duplicated) chromatids separate. It resembles mitosis of a haploid cell.
