Sentence examples for heritable variations from inspiring English sources

Darwin shows how small, heritable variations that improve survival and reproduction will accumulate over the millennia.

It is now increasingly clear that DNA segments coding for proteins account for only one aspect of heritable variations.

Darwinian evolution, in general, has suggested that adaptive mechanisms as a way of reaching robustness, could evolve by natural selection acting successively on numerous heritable variations.

Darwin, however, went on to explain in detail how seemingly "purposeful" structures, such as the placement of pollen and stigmatic surface of flowers for self-fertilization, evolved through the retention of slight heritable variations that promoted survival and reproduction.

The analytical tractability of our model allows for a systematic investigation of the relative contributions of heritable variations in gene expression, environmental changes and natural selection as drivers of phenotypic adaptation.

This heritable variation is known from heritability studies based on monozygotic twins.

Giraffes, he proposed, arose through heritable variation and natural selection — a tall-necked specimen appears in an ancestral tree-grazing animal, and, perhaps during a period of famine, this mutant survives and is naturally selected.
