Answer:
The correct answer will be option-C
Explanation:
Non-disjunction is the failure of the separation of the chromosomes during the separation phase of the division that anaphase I and anaphase II of meiosis.
The non-disjunction takes place during meiosis which takes place in the gamete formation.
A condition which develops from the non-disjunction with one extra copy of the Y chromosome is known as 47, XYY condition or Klinefelter syndrome.
This extra copy of the Y chromosome takes place when the chromosome separation failure takes place during anaphase II of meiosis II. This separation creates one extra copy of the chromosome.
Thus, Option-C is the correct answer.
