Interphase
Progenitor cells entering meiosis I pass through interphase stages similar to those seen in mitosis. This illustration depicts the G1 stage, however, for diagrammatic purposes, the chromosomes are shown in a condensed state; they do not actually condense until prophase. Following the G1 stage is the S phase during which both the centrioles of the centrosome duplicate and the DNA of the chromosomes replicates.

In these diagrams, the entire set of homologous chromosomes is represented by a single pair, one chromosome inherited from the mother and one from the father.
