The phylogenetic relationships of species in the Phasianidae, Order Galliformes, are the object of intensive study. However, convergent morphological evolution and rapid species radiation result in much ambiguity in the group. Further, matrilineal (mtDNA) genealogies conflict with trees based on nuclear DNA retrotransposable elements. Herein, we analyze 39 nearly complete mitochondrial genomes ...

An increasing number of studies indicate that chromosomes are spatially organized in the interphase nucleus and that some genes tend to occupy characteristic zones of the nuclear volume. FISH studies in mammalian cells suggest a differential localization of active and inactive loci, with inactive heterochromatin being largely perinuclear. Recent genome-wide mapping techniques confirm that the n...

Genomic imprinting refers to the process whereby genes are silenced when inherited via sperm or egg. The most widely accepted theory for the evolution of genomic imprinting-the kinship theory-argues that conflict between maternally inherited and paternally inherited genes over phenotypes with asymmetric effects on matrilineal and patrilineal kin results in self-imposed silencing of one of the c...

A zero mode quantization of the minimal energy SU(2) Skyrmions for baryon numbers four to nine and seventeen is described. This involves quantizing the rotational and isorotational modes of the configurations. For baryon numbers four, six and eight the ground states obtained are in agreement with the observed nuclear states of Helium, Lithium and Beryllium. However, for baryon numbers five, sev...
