Telomeres are repetitive DNA sequences (TTAGGG in humans) that protect the ends of chromosomes from deterioration or fusion with neighboring chromosomes.

In somatic cells of a species, the characteristic chromosome number is diploid (2n), meaning two sets of chromosomes, one inherited from each parent.

Meiosis is a type of cell division that reduces the number of chromosomes by half, producing four non-identical daughter cells, each with a unique combination of genetic traits.
The role of meiosis in the cell cycle is to produce gametes (sperm or egg cells) for sexual reproduction.

Telomeres function as a protective cap, preventing the loss of genetic information during DNA replication and protecting the chromosome from degradation.
