Analysis of pedigrees is one of the first stages in genetic screening - a
process in which individuals who have family members with a disorder seek
assistance to determine the likelihood of them or any children suffering
from the disorder. Genetic testing or diagnosis can follow initial
screening. Clinical genetic counselling  services began in the 1960s and
the _Victorian Clinical Genetics Service_ was established in Victoria in
1986. The Service also provides community education so people are aware of
genetic and developmental disorders. Counselling facilitates the making of
informed choices about issues relating to inherited genetic disorders. 
The Victorian Genetics Service provides genetic counselling, diagnostic
testing, carrier testing for certain conditions and pre-natal testing.
The kind of inheritance pattern of a particular trait  or
characteristic can often be worked out by analysing the pedigree chart.
