Expert Solution

Different mechanisms create different types of chromosomal aberrations; for example, nondisjunction can cause trisomy, while errors in DNA damage repair may cause inversions.

Trisomy is a condition in which there is a presence of an extra chromosome i.e. the presence of an extra 3rd chromosome instead of a pair of chromosome. Normally there is a pair of each chromosome in a normal cell but in case of trisomy there is an extra chromosome i.e. in case of trisomy-18 there are three chromosome 18 (47, +18). Trisomy occurs due to the non-disjunction of chromosome during meiosis, due to this a chromosome pair fails to separate and the gamete so produce will have an extra chromosome. In case of trisomy-18 it is the presence of an extra 18th-chromosome.

Inversion occur when there is a double strand break in a chromosome at two different positions and then the region between them is inverted and re-joined. If the double strand breaks are repaired correctly by the DNA repair mechanism then inversion might not occur, and the chromosome will be as such. But if there is an error in the DNA damage repair then inversion can occur. It can happen when this kind of breaks are repaired by non-homologous end joining.

About errors that can occur in the process of meiosis, and several types of errors are mentioned. Select of these types of errors (e.g. chromosome number, non-disjunctions, etc.) and provide a brief description of the error. Then do a little bit of online research related to the type of error and identify and describe one disease or condition that can result from this type of error (example – Trisomy 21 is where there is an extra chromosome in the 21st...
