Polyploidy is common among fish and amphibian species and very common among plant species.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Polyploidy is common among fish and amphibian species and very common among plant species?

Yes. Polyploidy, or whole-genome duplication, is well-documented and common among various fish and amphibian groups, and it is exceptionally widespread and frequent across plant species.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

The retrieved papers provide robust support for the claim that whole-genome duplication (polyploidy) is prevalent in plants (where it occurs at a notably higher frequency) and also significant among fish (teleosts) and amphibians.
