DNA Analysis
A total of 108 blood samples were collected from a believed sample set of:
- 29 After Hatch Year-Males (AHY-M)
- 18 After Hatch Year-Females (AHY-F)
- 30 Hatch Year-Males (HY-M)
- 31 Hatch Year-Females (HY-F)
DNA sexing revealed that we had in fact sampled:
- 26 After Hatch Year-Males (AHY-M)
- 21 After Hatch Year-Females (AHY-F)
- 29 Hatch Year-Males (HY-M)
- 32 Hatch Year-Females (HY-F)
Out of 108 samples, we incorrectly assumed the sex of 20 individuals (18.52%). More females were incorrectly sexed as male (12/20 = 60%). More After Hatch Year soras were incorrectly sexed (11/20 = 55%).
Quantitative and qualitative data was collected in hopes to justify our current field sexing techniques to a 95% accuracy or create more accurate field sexing methods.
Quantitative data collected:
- Culmen length (mm)
- Tarsus length (mm)
- Toe length (mm)
- Weight (g)
- Fat (scored 0-5)
Qualitative data collected:
- AP
- Bill color
- Head slope
