The true testing ground for the implicate - order strategy, it seems to me, may indeed be biology rather than physics, where abstract methods are so powerful as to perhaps make it dispensable: just as the old style building - block materialist was refuted not by philosophical polemic, but by the one authority in which he trusted, i.e., by physics itself, so the nothing - but reductionist in contemporary biology will modify his views should it be possible some day to provide him with a mathematical language that fills the currently existing gap between our formal knowledge of gene structure and combinations, and our intuitive apprehension of growth and shape.

A totally pure species would mean a value of 1.00, which is rather rare, as most cultivars (= cultivated varieties) contain genes from more than one species through breeding.

Because biological systems are so complex, it is a huge advantage to be able to tweak lots of genes simultaneously, rather than one at a time, she says.

Rather than supporting a genome duplication event at the time when yeast evolved to have twice the number of chromosomes, their data indicated that the duplicated genes had begun to diverge long before.

The discovery that a cavefish might have lost its sight because key eye genes were switched off via epigenetics, rather than mutation, will fuel an evolutionary debate

His vision of gene structure was focused on the non-repetitive nature of the code - script, rather than on the relatively simple parallel between the copying of chromosomes and the ability of crystals to replicate their structure.

Significantly, the study also shows that the genes that influence longevity act independently rather than interacting with each other, a phenomenon called epistasis.

What's more, Conboy's team actually fixed the faulty gene rather than simply disabling it, as Intellia did.

There is also the fact that Kono and Kawahara had to manipulate two genes to create their bi-maternal mice — so the differences in lifespan might be due to this genetic manipulation, rather than the absence of paternally imprinted genes.

Manton also noted Schrödinger's use of the term code - script, but she took it to mean «the sum of hereditary material» rather than a particular hypothesis about gene structure and function.

Even after the cells were taken out of microgravity for up to 30 generations before being combined with the control strain, they maintained 72 per cent of their adaptive advantage, pointing to permanent mutations in the genes rather than merely a temporary adjustment.
