As argued above, control efficacy is sensitive to the survival of the oldest mosquitoes, but evolutionary pressure decreases with an individual's age (Hamilton 1966), as beneficial mutations that act only when an individual has achieved most of its reproductive success increase fitness much less than mutations acting at a young age (Fisher 1930; Haldane 1941).
The ratio of θ/ρ, which indicates the importance of mutation relative to recombination, was approximately 30 32, indicating that recombination, while present, typically causes substitutions much less frequently than mutation.
Thus, at the S-RNase, gene conversion is expected to be much less important than mutation.
First, evolutionary pressure decreases with an individual's age (Hamilton 1966); beneficial mutations that act only when an individual has achieved most of its reproductive success increase fitness much less than similar mutations acting at a young age (Fisher 1930; Haldane 1941).
Therefore, mapping power should be much less affected by mutations that impact reproductive fitness, allowing smaller population sizes to be used.
Transverse mutations are much less frequent than the transition mutations and will affect these equations to a smaller extent.
With regard to the leptin gene, we note that pathological leptin deficiency occurs only in subjects with biallelic mutations and is therefore much less frequent than, e.g., MC4R mutation (which can lead also in the heterozygous status to disease manifestation).
Pathogenic mutations in the PTEN-induced kinase (PINK1) gene are much less common than PRKN mutations and probably account for only 1 to 2% of early-onset PD patients.
However, since the downstream transcriptional effects of the GHR-KO mutation are much less extensive than those of other long-lived models, understanding how this mutation contributes to longevity extension may prove less difficult.
Generally, the peroxidase activity was much less effected by these mutations.
