Los cromosomas son paquetes de información ya que contienen los genes que son las unidades que determinan las características hereditarias de los organismos. Las diferentes especies poseen un número constante de cromosomas tanto en células somáticas, las cuales se obtienen por mitosis, como en sus células sexuales o gametos que se producen por meiosis. La meiosis es la etapa del ciclo celular en que se divide el núcleo, repartiendo equitativamente el material genético previamente recombinado y da origen a células encargadas de la reproducción, es decir, los gametos, que son células haploides
