The colorful phenotypes of birds have long provided rich source material for evolutionary
biologists. Avian plumage, beaks, skin, and eggs—which exhibit a stunning range of cryptic …

Duck is the second-largest poultry species aside from chicken. The rate of egg production is
a major determinant of the economic income of poultry farmers. Among the reproductive …

Circular RNAs (circRNAs) are a subclass of RNA macromolecules that are reported to be
involved in the regulation of skeletal muscle development. However, the functions and …

Structural variations (SVs) are a major source of domestication and improvement traits. We
present the first duck pan‐genome constructed using five genome assemblies capturing∼ …

We compared the genomes of multiple domestic chicken breeds with red and white earlobes
to identify the differentiated regions between groups of breeds differing in earlobe color. This …

Eggshell colour is the unique appearance and economically valuable trait of eggs, whereas
the colour is often short of uniformity, especially in the blue-shelled breeds, hence, their …

Table eggs with color-uniformity shell are visually attractive for consumers. Lueyang black-
boned chicken (LBC) lays colorful eggs, which is undesirable for sale of table eggs, but …

Exploring the genetic loci underlying economic traits is foundational for innovation in
modern animal breeding technology. Genome‐wide association studies (GWAS) have been …

The eggshell color of avian species is an important trait that is predominantly determined by
the pigments biliverdin and protoporphyrin. Various factors affect eggshell pigment …

Chicken blue-greenish coloration (BGC) was known as a classic Mendel trait caused by a
retrovirus (EAV-HP) insertion in the SLCO1B3 gene. Lueyang black-boned chicken (LBC) …
