Which mutation causes either the inclusion of an extra chromosome in offspring or the deletion of an entire chromosome?
A) deletion
B) insertion
C) crossing-over
D) non-disjunction

Deletion is the loss of one of a chromosome or even an entire chromosome. The loss of nucleotide sequences by the genome of an organism implies failures in the pairing of chromosomes in meiosis, which can lead to syndromes such as cry du chat (cat's cry), characterized by neurological dysfunctions and changes in facial structure.
