A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.

Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.

This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.

Verdich [7]

Answer:

(c) Inherited a mutation in a gene required for mismatch repair

Explanation:

Gene mutations are occasional changes that occur in genes, that is, the procedure by which a gene undergoes a structural change. Mutations involve the addition, deletion or substitution of one or a few nucleotides of the DNA strand. Mutation provides the emergence of new forms of a gene and, consequently, is responsible for gene variability.

It is common for several members of the same family to have the same genetic mutations, as the gene affected by the mutation may condition a trait that DNA cannot repair. An example of this is the family shown in the question above, where several people were diagnosed with the same type of cancer while still young. What probably happened in this family was that people diagnosed with cancer inherited a mutation in a gene needed to repair incompatibility.
