What process can account for the phenomenon wherein a normal xy male produces a sperm carrying two y chromosomes?
a.) first division nondisjunction
b.) disjunction
c.) second division nondisjunction
d.) copy-number variation
e.) translocation

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.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.
