WebNov 5, 2024 · The phenotypic traits measured or calculated at a given organizational level characterize the properties that emerge at this level. Whether or not higher-level properties are reducible to lower level properties is a long-standing debate in the philosophy of sciences (see e.g. Francescotti 2007 ).
WebCancer evolution is driven by natural selection acting upon phenotypic trait variation. However, the extent to which phenotypic variation within a tumour is a consequence of intra-tumour genetic heterogeneity remains undetermined. Here we show that colorectal cancer cells frequently have highly plastic phenotypic traitsin vivoin patient tumours. crazy model dietsWebGenetic Variance.
