Copy Number Variation has been associated with morphological traits, developmental
defects or disease susceptibility. The autosomal dominant Pea-comb mutation in chickens is …

Comb traits have potential economic value in the breeding of indigenous chickens in China.
Identifying and understanding relevant molecular markers for comb traits can be beneficial …

The aim of this study was to identify genes involved in comb development to provide insights
into the molecular mechanism of chickens' comb formation. Fixation index (F ST) and …

The comb, as a secondary sexual character, is an important trait in chicken. Indicators of
comb length (CL), comb height (CH), and comb weight (CW) are often selected in …

Background Chromosomal segmental copy number variation (CNV) has been recently
recognized as a very important source of genetic variability. Some CNV loci involve genes or …

DNA sequence variations include nucleotide substitution, deletion, insertion, translocation
and inversion. Deletion or insertion of a large DNA segment in the genome, referred to as …

An increasing number of studies have shown that quantitative trait loci (QTLs) at the end of
chromosome 1 identified in different chicken breeds and populations exert significant effects …

Copy number variation (CNV) is considered an important genetic variation, contributing to
many economically important traits in the chicken. Although CNV s can be detected using a …

To facilitate gene identification, this study aimed to narrow the scope of the genome region
affecting chicken comb type by using two bird populations. First, an F2 resource population …

Copy number variation refers to regions along chromosomes that harbor a type of structural
variation, such as duplications or deletions. Copy number variants (CNV s) play a role in …
