Ovariole (IMAGE) Stowers Institute for Medical Research Caption In Drosophila females, sequential meiotic stages are observable in a string of developing egg chambers called the ovariole. Meiosis starts at the anterior region (top-right) and meiotic cells form the synaptonemal complex (shown in purple) to pair up homolog chromosomes. Centromeres are shown in orange and DNA is labeled green Credit Courtesy of Dr. Satomi Takeo, Stowers Institute for Medical Research.
