Germinal cells can most likely divide indefinitely due to the activity of an enzyme called Telomerase.
The telomeric sequences are extra sequences which are reduced during several rounds of replication.
However, these are restored by the enzyme telomerase which keeps the length of the telomere sequence enough to undergo several rounds of replication.
Generation after generation, germ cells must precisely transmit genetic information.
They have a lot of telomerase activity to stop the genetic material from being lost during meiosis. The parents' genetic material is kept intact thanks to the high level of telomerase.
The primary region of the chromosome, which contains the genes necessary for life, would become shorter without telomeres with each cell division. Telomeres thereby permit cell division without gene loss.
