The history of the present illness is documented in the MEDICAL HISTORY section of the patient's record.
The medical history section contain information about all the diagnoses, medical care and treatment that the patient had received. These information help the current physician to have an idea of what has been going on concerning a patient's case in the past and he will documents his own observation in this section.
The first one is second succession. The second question I don't understand.

Answer: Structural chromosomal mutation
Explanation: In translocation, a small piece of chromosome is detached from one chromosome and is attached to another non-homologous chromosome. Translocation can be simple, shift or reciprocal.
Simple translocation involves single break in the chromosome. The broken piece gets attached to the end of the non-homologous chromosome.
In Shift translocation, the broken segment of one chromosome gets inserted interstitially in a non-homologous chromosome.
Segment from one chromosome is exchanged with a segment from another non-homologous chromosome simultaneously in Reciprocal translocation.
