Captive dolphins are particularly susceptible to MetS because their diets are normally constrained by a human selection process.
We also found several genomic regions of decreasing diversity which might be caused by a recent human selection in rice breeding.
We also found several genomic regions decreasing genetic diversity which might be caused by a recent human selection in rice breeding.
Although it may seem difficult to fix such a character by human selection, Lukens and Doebley (1999) suggested that domestication of maize may have involved selection for allele(s) with reduced environmental plasticity, and cited a model suggesting that morphological evolution may occur rapidly when selection favours one morph of a phenotypically plastic species.
In summary, genes that undergo expression alteration between wild and domesticated fibre do not do so randomly but, instead, they appear to have been shaped by human selection in a correlated fashion, forming clusters of genes displaying one to several of the possible expression patterns.
Several factors may have contributed to a lack of diversity in tef germplasm, including a bottleneck in the wild ancestor population, a small number of plants used to found the domesticated species, and/or a narrowing of acceptable germplasm by human selection.
Double flower domestication is of great value in ornamental plants and presents an excellent system to study the mechanism of morphological alterations by human selection.
The genetic structure of cultivated grapevine has been influenced by human selection [ 14] and it can be largely understood as a complex pedigree, due to the vast number of higher order pedigree relationships [ 10].
This could be explained by human selection.
These transcriptional changes may indicate selection pressure or simply breed differences which may be driven by human selection.
Conventional wisdom is that characters favoured by human selection, such as increased size or loss of dispersal, are disadvantageous or even lethal in the wild.
