Technical Questions¶
What is CHD gene-based sexing?¶
CHD (Chromobox Helicase DNA-binding) genes are located on the avian sex chromosomes (Z and W). In most bird species, the CHD-Z gene is present on the Z chromosome and the CHD-W gene is unique to the W chromosome (female-specific). PCR amplification using conserved primers (such as P2/P8) produces:
- Male (ZZ): Single band (CHD-Z, ~400-650 bp depending on species)
- Female (ZW): Double bands (CHD-Z + CHD-W, ~350-650 bp depending on species)
This method works across most bird species because the CHD genes are highly conserved in avian evolution.
What is qPCR and why is it used for disease testing?¶
Quantitative PCR (qPCR) monitors DNA amplification in real time using fluorescent probes. This allows:
| Advantage | Benefit for Disease Testing |
|---|---|
| Quantification | Measure viral load (copies/µL) |
| Higher sensitivity | Detect low-level infections |
| Closed-tube system | Reduced contamination risk |
| Faster results | No post-PCR processing needed |
| Multiplex capability | Screen for multiple pathogens in one reaction |
