In a world of complicated and conflicting genetic markers, the Genetics Pedigree Worksheet has become an indispensable tool for testing, documenting, and improving your DNA testing results. All of the following factors have been shown to affect your DNA testing results:
Information from other parents: There is an incredible amount of testing and documentation information that goes into DNA testing results. Some of the information may be shared with you by your physician, but many times, you will need to provide a supplemental form or response to establish a relationship between you and your genetic history. By providing this information at your own request, you will better understand what information the doctor or lab reports.
Direct paternal genetic information: This information is recorded in your own DNA sample. You can retrieve it from your saliva. What information you receive depends on whether you are a male or female. In some cases, this information can be less accurate than other information.
Intersex data: Intersex refers to those who do not have a gender-specific chromosome (called X or Y) and are sexually differentiated. Most individuals with this condition will test positive, but there may be instances where they are negative. If you have a child with this condition, your child will test positive as well.
Carrier testing: The information about carriers is fairly limited. Information about carriers is in the DNA from the mother or father and is recorded in the child’s genome. It is a complex and precise testing tool that produce the highest quality results and allow you to see who your biological children are.
Gestational carrier testing: The testing method used in gestational carrier testing is very similar to most other testing methods. It asks the mother if she has had sexual intercourse outside of her pregnancy. If so, she must provide a supplemental form.
Private clinics may provide their own labs, which then share their labs with others. This is an effective way to avoid double testing, since the samples can be sent from one lab to another.
No matter which private labs you choose, your Genetic Information Sheet Key will be free. Many of the major testing centers offer this service free of charge for their clients, which allows you to gather the information you need without costing you anything.
