Flea Pupa. The flea larvae spin cocoons around themselves in which they move to the last phase of the flea life cycle and become adult fleas. The larvae can remain in the cocoon anywhere from one week to one year. Temperature is one factor that determines how long it will take for the adult flea to emerge from the cocoon.

This page is devoted to explaining the different types of Nondisjunction disorders that occur in our world. Nondisjunction disorders are when cell division development of the zygote has an imbalanced amount of genetic information.This imbalance affects the distribution of the chromosomes or genetic information that each cell has.aving abnormal amounts of karyotypes in the chromosomes will overload the cells and this in turn can kill the zygote or in some cases, a person with Nondisjunction disorder is born. There are various karyotypes in our chromosomes that make our genetic makeup.
