Sexing a wider range of avian species based on two CHD1 introns with a unified reaction condition

Abstract 10.1002/zoo.20149.abs Identifying the sex of a bird is important to ensure successful breeding strategies and effective conservation programs. Sex may be identified from the intron size of the CHD1 gene located on the avian sex chromosomes Z and W. However, because of the great nucleotide diversity across different avian species, no given intron is […]

Cut feather containing rachis as a sampling way for avian sexing

Abstract 10.1002/zoo.20083.abs Sex determination of birds is important to ensure successful breeding strategies, especially for endangered species. Most birds are vulnerable to stress during handling, however, so obtaining a sufficient amount of genomic DNA (gDNA) while causing the least amount of harm is a critical issue. Avian gender can be determined based on different CHD1 […]

Sex Identification of Four Penguin Species Using Locus-Specific PCR

Traditional methods for sex identification are not applicable to sexually monomorphic species, leading to difficulties in the management of their breeding programs. To identify sex in sexually monomorphic birds, molecular methods have been established. Two established primer pairs (2550F/2718R and p8/p2) amplify the CHD1 gene region from both the Z and W chromosomes. Here, we […]

Avian gametologs as molecular tags for sex identification in birds of prey of Iran

Global environmental change and rapid destruction of natural habitats necessitate the conservation of endangered and threatened birds of prey. Recently, molecular sex identification methods based on amplification of introns of chromodomain-helicase DNA binding protein1 (CHD1) have provided valuable tools for ecological study and conservation breeding programs of birds. These methods employ a primer pair flanking […]
