Explanation:
During meiosis, a diploid cell ultimately forms four haploid gametes that go on to take part in fertilization. Because they are haploid. that means they have one copy of all of the chromosomes and the genes contained within them.
First, the DNA is replicated, and then two cell divisions take place form the haploid gametes. So at first, there are two copies of each gene, creating four after the DNA is replicated.
After the first cell division (meiosis I) there are two cells with 2 copies of every gene. Then to form the haploid gamete, there is another cell division (meiosis II) creating 4 cells each containing one copy of every gene
