DNA Based Avian sexing, Bird Sexing
DNA sexing has quickly risen to become the method of choice
for determining the sex of avian monomorphic species. With
accuracy rates greater then 99.9 %, it is no surprise that
this method of sexing has become number one with bird owners
and aviculturalists worldwide. Over the years, HealthGene
Laboratory has conducted literally thousands of DNA based bird sexing
tests for an array of cliental, ranging from individual bird
owners and breeders to entire zoo populations.
You may be wondering what makes DNA based
avian sexing so accurate. The answer to this question can
be found in the technology underling this approach. Advances
in molecular diagnostics have brought a technique known as
PCR to the forefront of DNA diagnostics. Using PCR, differences
in the DNA of male and female birds can be amplified and detected
in the laboratory. Here's how it works.
DNA based avian sexing utilizes the fact that male and female
birds have different genes or chromosomes, much like mammals.
The only difference is that the female bird (carrying a ZW
chromosome pair) determines the sex of the offspring, since
the male (carrying a ZZ chromosome pair) can only contribute
a 'Z' chromosome (this is just the opposite of what occurs
in humans). Using PCR in the laboratory, a region of DNA that
differs in size between the Z and W chromosomes is amplified.
Thus, this method yields one PCR product for males and two
PCR products for females, making visual detection in the laboratory
easy.
HealthGene laboratory offers bird owners
two options with regards to submitting samples for sexing.
These options include feather sexing or blood sexing. It is
a common misconception that blood samples are more accurate
then feather samples for determining sex. In reality, blood
sexing and feather sexing are 100% identical with regards
to accuracy. Since both procedures ultimately result in isolating
and analyzing DNA, the source of the DNA (whether it's from
blood or feather cells) has no impact on the final results
of this test. Instructions for submitting either blood or
feather samples are included on the last page of this newsletter.
Also, HealthGene provides free sample collection kits, complete
with instructions, for those interested in submitting blood
samples. Although HealthGene accepts feather and blood samples,
blood samples are preferred since they ensure a result. Again,
there is no difference in the accuracy of the final result;
however, feather samples may have to be resubmitted if not
enough cells are present for analysis. Alternatively, eggshells
may be used to determine sex if the inner membrane is still
present and intact. Turnaround times for this particular test
range from 1-2 business days.
