This precise technique analyzes the **Chromodomain-helicase-DNA-binding (CHD) gene** located on the bird’s sex chromosomes (Z and W), providing results that are critical for breeding, conservation, and pet management. ### The Genetic Basis Unlike mammals (XY system), birds utilize the **ZW sex determination system**. Males possess two Z chromosomes (**ZZ**), while females possess one Z and one W chromosome (**ZW**). Our analysis targets the **CHD-Z** and **CHD-W** gene fragments, which have slight size differences (polymorphisms) that allow for definitive identification. ### Core Testing Technologies - **Polymerase Chain Reaction (PCR):** The standard method used to amplify the CHD-Z and CHD-W fragments. Sex is distinguished by observing the DNA amplification products: **two bands (ZW) indicate a female**, while **one band (ZZ) indicates a male**. - **Real-Time PCR (RT-PCR):** A faster, high-throughput technique using fluorescent probes to monitor amplification in real time, enabling **automated and rapid results** suitable for large-volume testing. - **Gene Sequencing:** Reserved for complex cases, rare species, or research, sequencing provides the **highest level of genetic analysis** for absolute certainty. ### Key Advantages of DNA Sexing - **Universal Applicability:** Effective for **all bird species**, regardless of age (from newly hatched chicks to mature adults). - **High Accuracy:** Guarantees a verified **accuracy rate of up to 99.9%** when performed in our certified laboratory. - **Non-Invasive Sampling:** Requires only a tiny, safe sample (feather with follicle, blood spot, or eggshell membrane). This scientific method is the gold standard, widely utilized in zoological conservation, pet breeding, and scientific research globally. ## **🕊Avian DNA Sexing Process: Our 6-Step Guide to Accurate Results** ### Avian DNA Sexing Process This detailed process, utilizing certified protocols and state-of-the-art equipment, ensures high-accuracy sex identification for all bird species. ### 1.
