In the last chapter, no attempt was made to describe how animals mediate patterns of pollen flow within and between plants, nor how efficient various pollination mechanisms are in the dispersal of pollen and in achieving seed-set. The behaviour of pollinators strongly influences pollen flow, and...
By continuing to study hybridizing species and hybrid zones, researchers can further understand which sets of genes have permissible gene flow and which are more restricted. Then, by studying genes in the latter category, scientists can learn which genes or gene sets may be important in maintaining...
The impact of gene flow on the level of local inbreeding in populations is mostly considered in Wright's neighbourhood model (1943; 1946). The neighbourhood is the area (Na) from which the parents of central individuals may be treated as if drawn at random. The effective size of a ...
The results confirmed that, in general terms, the level of gene flow between the three species is high, although varying across space in a manner consistent with their natural ranges (Figures 3B and S3A–S3E). For example, gene flow between golden jackals and gray wolves and between African...
The most recent Alu insertions reveal different degrees of polymorphism in human populations, and a series of characteristics that make them particularly suitable genetic markers for Human Biology studies. This has led these polymorphisms to be used to analyse the origin and phylogenetic relationships be...
Genetic diversity, genetic structure, and gene flow in plant populations and their influencing factors are important in conservation biology. Cypripedium macranthos is one of the few wild orchids with high ornamental value in northern China. However, over the past decade, excessive collection, trading...
DNA methylation is one of the most commonly studied epigenetic marks, due to its role in disease and development. Illumina methylation arrays have been extensively used to measure methylation across the human genome. Methylation array analysis has primar
Notably, due to a likely presence of contaminant sequences, the initial set of genes may include genes from species other than Pt and therefore the set of parameters might be biased. Figure 1 Flow chart of Pt EST sequence analysis. Gene prediction in the P. triticina EST sequences was ...
the extent and variability of pollen-mediated gene flow in switchgrass under field conditions have only been recently described in the literature [28]. The pattern of pollen-mediated gene flow is dictated by numerous factors, for instance, climatic conditions, pollination biology, and size and proxi...
To assess inference of the cell cycle, we considered a mouse embryonic stem cell cycle dataset [36], where embryonic stem cells were collected along three stages of the cell cycle (G1, S, G2/M). Cell cycle phase was manually annotated a priori based on flow sorting cells according to ...
