A new look at the evolution of avian sex chromosomes.

abstract：:Genome projects allow us to sample copies of a retrotransposon sequence family residing in a host genome. The variation in DNA sequence between these individual copies will reflect the evolutionary process that has spread the sequences through the genome. Here I review quantitatively the expected diversity of elements...

abstract：:Variations of gene copy number in the human genome are increasingly recognized as a genetic factor in phenotypic variation. Human CC chemokine ligand 3-like 1 gene (CCL3L1), which is located on human chromosome 17q11.2, is highly variable in copy number owing to having a hot spot for segmental duplications. CCL3L1, a ...
