Is it true that Mutational variance measures the rate at which mutations add to phenotypic variation?
Yes. Mutational variance is a standard quantitative genetics metric measuring the rate at which random mutations introduce new phenotypic variation into populations.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The analysis
The retrieved literature consistently discusses mutational variance ($V_M$) as the metric quantifying the amount of phenotypic variation introduced by new mutations in mutation accumulation experiments. Papers [0], [1], and [5] directly study or employ this concept. No papers refute the claim.
Evidence for · 3
Discusses standardized estimates of mutational variance (VM) in mutation accumulation experiments, directly measuring the phenotypic variation introduced by new mutations.
