acts as a source of variation in spiecies.
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
During meiosis I, the DNA content is halved as homologous chromosomes separate, leading to haploid daughter cells. In meiosis II, sister chromatids separate without DNA replication, resulting in four haploid daughter cells with the same DNA content as the parent cell before starting meiosis.
DNA replication does not occur during meiosis. Meiosis is a specialized cell division process that involves two rounds of division to produce gametes with half the number of chromosomes as the parent cell. DNA replication happens during the interphase preceding meiosis.
A gamete would contain the haploid amount of DNA, which is one complete set of genetic material. During meiosis, DNA is replicated once during S phase but is not copied again between meiosis I and meiosis II, so each gamete ends up with a single set of chromosomes.
Telophase is a phase of mitosis. DNA replication must occur before mitosis begins. If it does not then the DNA chromosomes may not be consistent throughout the division of the cells.
Meiosis creates genetic diversity due to the processes that occur during meiosis. Such as crossing over which creates new gene combinations due homlogous chromosomes swapping or exchanging DNA segments. Independent assortment is also during meiosis and allows the random assortment of homologous chromosomes during metaphase 1.

Meiosis does not repair DNA, instead it produces copies of itself.

DNA replicates once during meiosis. This is why the end result is four haploid cells.
Recombinant DNA is made during the crossing over stage of meiosis, specifically during prophase I. This is when homologous chromosomes exchange genetic material, leading to the formation of new combinations of genes.

During meiosis, the amount of DNA is reduced by half in each cell division. This reduction occurs during meiosis I when homologous chromosomes separate, leading to cells with only one set of chromosomes (haploid). This reduction is necessary to ensure that when egg and sperm cells combine during fertilization, the resulting zygote will have the correct amount of DNA.

None. DNA replication occurs before meiosis I begins.
