twice the parent’s DNA

created their own DNA from scratch

Detailed explanation-1: -The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Detailed explanation-2: -Each daughter cell has half the number of chromosomes as compared to their parents (one copy of each chromosome). The resulting cells from meiosis are not genetically identical because of the recombination of genes that occurred during prophase 1.
Detailed explanation-3: -Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
Detailed explanation-4: -Summary of Meiosis II Meiosis II begins with the 2 haploid cells where each chromosome is made up of two connected sister chromatids. DNA replication does NOT occur at the beginning of meiosis II. The sister chromatids are separated, producing 4 genetically different haploid cells.
Detailed explanation-5: -Final answer: After meiosis I, the resultant daughter cells have twice the amount of DNA in comparison to haploid gamete.
