The phrase "a source of heritable" is not complete and lacks context, making it difficult to determine its correctness in written English.
It could be used in discussions about genetics, inheritance, or traits passed down through generations, but it needs to be part of a fuller expression.
Example: "The gene identified in the study is a source of heritable traits that influence physical appearance."
Alternatives: "a source of inherited" or "a source of genetic".
This work shows that a morphogen gene itself can be a source of heritable pattern variation in nature.
Evolutionary theory predicts that such a source of heritable variation can onset a rapid genetic divergence if natural selection favors extreme phenotypes as, for example, very high or low gill raker numbers (Stockwell et al. 1950).
Second, and even more important from an evolutionary perspective, there needs to be a source of heritable variation upon which selection can act after selection gradients have been restored.
This Cryopreserved Mutant Mouse Bank (CMMB) is a source of induced, heritable SNPs in virtually every gene in the genome.
Epiallelic instabilities, as described above, create a complex source of heritable variation.
In recent years, CNV has been increasingly recognized as a major source of heritable variation that impacts complex traits (Redon et al. 2006).
CNV has been recently identified in human and other mammalian genomes, and it is now recognized that CNV might be a major source of heritable variation in complex traits [ 4].
Therefore, for socially affected traits, the heritable variation due to social interactions can be a significant source of heritable variation in domestic, natural, and laboratory populations, for both behavioural traits and production traits [ 15, 16, 20, 21] and taking such interactions into account may reveal that their genetic variation is significantly greater than previously thought.
In closing, we hypothesize that population-level variation in the repertoire of available TCR/immunoglobulin gene segments may represent an underappreciated source of heritable diversity in the adaptive immune system.
Of course, evolutionists since the modern synthesis have known that the source of heritable variation in structures like eyes is mutation of the genes involved in "making" those eyes.
Classically, quantitative geneticists envision DNA sequence variants as the only source of heritable phenotypes.
