Answer the following question: Answer the following question given this paragraph: Chromosome Structural Rearrangements Cytologists have characterized numerous structural rearrangements in chromosomes, including partial duplications, deletions, inversions, and translocations. Duplications and deletions often produce offspring that survive but exhibit physical and mental abnormalities. Cri-du-chat (from the French for "cry of the cat") is a syndrome associated with nervous system abnormalities and identifiable physical features that results from a deletion of most of the small arm of chromosome 5 (Figure 7.11). Infants with this genotype emit a characteristic high-pitched cry upon which the disorder's name is based. Q: Structural rearrangements of what include partial duplications, deletions, inversions, and translocations; duplications and deletions often produce offspring that survive but exhibit physical and mental abnormalities? A:

Available choices: --neutrons --phenotypes --cells --chromosomes
Answer:
chromosomes
