Another nail in the coffin of "biological determinism":
"Study finds cell memory can be more like a dimmer dial than an on/off switch"

The researchers carried out experiments in which they set the expression of a single gene at different levels in different cells. While conventional wisdom would assume the gene should eventually switch on or off, the researchers found that the gene’s original expression persisted: Cells whose gene expression was set along a spectrum between on and off remained in this in-between state.
The results suggest that epigenetic memory — the process by which cells retain gene expression and “remember” their identity — is not binary but instead analog, which allows for a spectrum of gene expression and associated cell identities.
