Walchobia bacteria changes male to female in 80% of arthropods.

Infact verdict: Mixed (50/100).

The claim that Wolbachia bacteria change male to female in 80% of arthropods is not fully supported by the evidence. While Wolbachia can indeed feminize male arthropods, the percentage of affected species is not as high as claimed. Evidence suggests that Wolbachia affects up to 76% of arthropods, but this includes various reproductive and developmental changes, not exclusively male-to-female transformation. Therefore, the claim is misleading as it overstates the specific impact of Wolbachia on gender change.

Walchobia bacteria changes male to female in 80% of arthropods.
The evidence indicates that Wolbachia bacteria can cause male-to-female transformation in arthropods, but the claim that this occurs in 80% of arthropods is misleading. Sources suggest that Wolbachia affects up to 76% of arthropods, but this includes various effects, not just gender change. Therefore, the claim exaggerates the specific impact of Wolbachia.
