The phrase "a higher mutation level" is correct and usable in written English.
It can be used in contexts related to genetics, biology, or any field discussing variations or changes in organisms or systems.
Example: "The researchers observed a higher mutation level in the virus, which could lead to more rapid evolution."
Alternatives: "an increased mutation rate" or "a greater mutation frequency."
Despite this high value, the majority (81.6 – 93.7%) of the M2 population were viable and produced seeds suggesting that flax plants can support a high mutation level [ 55].
In this model, only the effect of age was significant (P=0.021, GLM), whereas cases had higher mutation levels but this did not reach statistical significance (P=0.104, GLM) (Table 2).
In this way, we obtained vigorous and mostly fertile plants, while expecting to maintain the high mutation level in a heterozygous state.
Such studies will benefit from the use of additional hypermutable markers with reported high mutation levels, such as MycL1, DXS981 or UT5307.
Large changes in the percentage level of mutated mtDNA are observed in small human pedigrees transmitting heteroplasmic mtDNA mutations (Chinnery et al., 2000), and so even low levels of mutant mtDNA carry-over could lead to maternal descendants with high mutation levels, causing severe multi-system disease (DiMauro and Schon, 2003).
In the right panel, a high mutation rate increases levels of both background selection and clonal interference.
Therefore, the data on T. congolense presented here are not consistent with a high mutation rate alone leading to the level of genetic diversity observed in our data set.
Case status was borderline significantly associated with higher nonunique mutation levels (P=0.091, GLM) but in the comparison with the 10 surgery-only patients an increase in nonunique mutations was statistically significant (P=0.012, GLM).
If indeed a core structure is necessary for maturation of the rRNA, mutations in a minimum length structure will affect the core structure integrity moreso than longer ITS2 sequences that may accommodate a higher level of mutation.
The overall pattern of variability suggests that there might be a higher level of mutation when F mtDNAs are in a male than in female, and that increased variability has to be produced de novo in males each generation.
