Centrosomes i

The chromatin begins to condense following interphase.

Mid-Prophase I

Chromosomes Condense

H Synapsis aligns homologs, and chromosomes condense. Homologs are shown in different colors indicating those coming from each parent. In reality, their differences are very small, usually comprising different alleles of some genes.

Late Prophase I-Prometaphase

Prometaphase

3 The chromosomes continue to coil and shorten. Crossing over results in an exchange of genetic material. In prometaphase the nuclear envelope breaks down.
