Sentence examples for strata formation from inspiring English sources
AMEL was clearly a problem for the Lahn and Page (1999) model of strata formation by Y inversion until it was found that AMELX and AMELY showed evidence for gene conversion, which could explain the peculiar divergence pattern of AMEL (Marais and Galtier 2003; Ross et al. 2005).
Numerical simulators of the dynamics of strata formation of continental margins fuse information from the atmosphere, ocean and regional geology.
The proposed scenario is consistent with strata formation, but there may be equally good scenarios not consistent with strata formation.
One efficient mechanism for strata formation is an inversion on the Y chromosome (Charlesworth 1978; Kirkpatrick and Barton 2006), which suppresses X-Y recombination in males in the region of the inversion (Lahn and Page 1999; Ross et al. 2005; Lemaitre et al. 2009a).
The absence of segmental structure within chicken autosomal sequences homologous to human X-linked sequences demonstrates that stratum formation fundamentally alters sequence composition, thus allowing identification of compositional signals unique to evolutionary strata by the proposed segmentation and clustering method.
Yet, recent stratum formation or added genes from autosomes have not been reported for the well-studied Y chromosomes of two other carnivores, cat and dog (Cortez et al. 2014).
Finally, due to the paucity of information on bear sex chromosomes, we cannot exclude the possibility of recent stratum formation, with the existence of segments that have not yet attained a high level of divergence between the Y and X chromosomes.
The coal-bearing strata include Benxi Formation, Taiyuan Formation and Shanxi Formation with a total thickness of 110 160 m (Fig. 2).
In PPAR-α /– mice we observed delayed stratum corneum formation between day 18.5 of gestation and birth.
This study was designed to test whether PPAR-α plays a physiologic role in epidermal differentiation and stratum corneum formation in utero.
Furthermore, we have reported that both epidermal differentiation and stratum corneum formation in utero are stimulated by pharmacologic activation of PPAR-α.
