Answer to Question 1

ANS: D
Translocation occurs when two chromosomes break and each of the broken pieces reunites with another chromosome. If chromatin is neither lost nor gained in the process, the exchange is called a balanced reciprocal translocation.

Answer to Question 2

ANS: D
The normal haploid number of chromosomes for humans is 23. Thus in a patient who has triploidy, he or she has three times that number (i.e., tri-), or 69.

Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.
