This question lacks options, the options are:
A. Halved
B. Doubled (x2)
C. Quadrupled (x4)
D. Octupled (x8)
The answer is B.
Explanation:
Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).
However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
