Aging-related mosaic loss of ChrY (LOY) has been known for more than half a century, but it was constantly considered as a neutral karyotype related to normal aging. These views have been challenged with genome-wide association studies identifying mosaic LOY in human somatic cells is the most...
R. et al. The Pseudomonas syringae Hrp pathogenicity island has a tripartite mosaic structure composed of a cluster of type III secretion genes bounded by exchangeable effector and conserved effector loci that contribute to parasitic fitness and pathogenicity in plants. Proc. Natl Acad. Sci. USA ...
some embryos present a mixture of normal cells and altered cells. Therefore, when only one cell of the embryo is biopsied, it is possible that a non-viable mosaic embryo is taken as healthy, or vice versa. What are the disadvantages of PGD? The remaining drawbacks of PGD have to do with...
Ecology is not synonymous with environment, environmentalism, or environmental science.[1][2][3] Ecology is closely related to the disciplines of physiology, evolution, genetics and behavior.[4] Like many of the natural sciences, a conceptual understanding of ecology is found in the broader ...
In turn, the occurrence of 4 lineages with relatively ancient divergence clearly indicates that peninsular Italy did not act as a single refugium for the species, but rather as a mosaic of refugia, at least during the last Pleistocene glacial-interglacial cycles. The most ancient event inferred ...
In turn, this reduction in niche overlap makes it more likely that they will coexist in high-density together in future. Our first key result is to formalise this principle with population genetics and show its equivalence with unsupervised correlation learning (Table 1g). Then, to demonstrate ...
