Answer:

Prophase II meiosis-chromosomes-6 and 12 DNA molecules per cell.

Explanation:

Meiosis is a unique type of division that occur in cells in which the chromosome number is decreased to half with the creation of haploid cells. It can be referred to as reduction division and it mostly occurs in organisms which go through sexual reproduction.

In prophase II , the nucleoli and nuclear membrane disappear.

The chromatids reduces in length to become short and thick .

The centromeres migrates to the polar regions and set the spindle fibres in place for the second meiotic division.

Therefore, at Prophase II of meiosis

The daughter cells are haploid. Its haploid cells should possess six chromosomes and 12 DNA molecules.

Meiosis creates gametes (eggs and sperm) with only a single chromosome set (haploid or n) from parental cells with two chromosome sets (diploid or 2n). During fertilization, the haploid sperm (n) and egg (n) fuse, producing a diploid zygote (2n). The cells of the zygote then divide by mitosis (which does not change the ploidy level) to produce an adult organism (still 2n) of the next generation.
