Usage examples of "phenotypic".

The phenotypic effect of some particular gene might be, say, green eye colour.

In practice most genes have more than one phenotypic effect, say green eye colour and curly hair.

Natural selection favours some genes rather than others not because of the nature of the genes themselves, but because of their consequences-their phenotypic effects.

But we shall now see that the phenotypic effects of a gene need to be thought of as all the effects that it has on the world.

In all this, remember that the phenotypic effects of a gene are the tools by which it levers itself into the next generation.

What might it mean in practice to speak of a gene as having an extended phenotypic effect on the world outside the body in which it sits?

Giantism in beetle larvae is an extended phenotypic effect of protozoan genes.

In all three cases the changes in the host, if we accept that they are Darwinian adaptations for the benefit of the parasite, must be seen as extended phenotypic effects of parasite genes.

The genes, then, are physically close to their extended phenotypic effects, as close as genes ordinarily are to their conventional phenotypes.

Beaver lakes are extended phenotypic effects of beaver genes, and they can extend over several hundreds of yards.

Cuckoo adaptations to manipulate the behaviour of foster-parents can be looked upon as extended phenotypic action at a distance by cuckoo genes.

The weapons in the fight are phenotypic effects, initially direct chemical effects in cells but eventually feathers and fangs and even more remote effects.

It undeniably happens to be the case that these phenotypic effects have largely become bundled up into discrete vehicles, each with its genes disciplined and ordered by the prospect of a shared bottleneck of sperms or eggs funnelling them into the future.

With only a little imagination we can see the gene as sitting at the centre of a radiating web of extended phenotypic power.

The whole world is criss-crossed with causal arrows joining genes to phenotypic effects, far and near.
