Homozygous retnRO44 animals also exhibit mushroom body (MB) specific abnormalities. A subset of MB neurons diverge within the nerve tracks and axons from the posterior part of the β-lobe neurons cross the midline and join with the opposite β-lobe neurons, causing β-lobe fusion. This is more common in females than in males.
Ovaries contain a large number of mature eggs and they are retained.
