Advantage: Dichotomous keys are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms.

Telophase 2 is the final step of meiosis 2 in which homologous chromosomes reach the opposite poles and four haploid cells are formed.
Explanation:
The telophase 2 ends up in four haploid (n=2) cells. It is in this phase the genetic material of the parent cell is divided into 2 daughter cells. The events taking place are nuclear membrane reappears (karyokinesis has taken place by now), spindle fibres and astral rays disappear, chromosomes decondensed to become chromatids (thin fibres), constriction on equatorial plate consequently four daughter cells formed.
they contain half of a set of chromosome...that's jot true
