Sequence and comparative analysis of the chicken genome provide unique perspectives on vertebrate evolution

Article Abstract:

The study presents the results obtained from an extensive analysis of a draft sequence of the chicken genome of the red jungle fowl, Gallus gallus, which has evolved separately from mammalian genomes for ~310 million years. This chicken is an important model organism that bridges the evolutionary gap between mammals and other vertebrates and serves as the main laboratory model for the ~9,600 extant avian species.

A genetic variation map for chicken with 2.8 million single-nucleotide polymorphisms

Article Abstract:

The study describes a genetic variation map for the chicken genome containing 2.8 million single-nucleotide polymorphisms (SNPs). It concluded that at least 90% of the variant sites are true SNPs, and at least 70% are common SNPs that segregate in many domestic breeds.
