Genealogy is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members. The results are often displayed in charts or written as narratives. The field of family history is broader than genealogy, and covers not just lineage but also family and community history and biography.
Adoption is a process whereby a person assumes the parenting of another, usually a child, from that person's biological or legal parent or parents. Legal adoptions permanently transfer all rights and responsibilities, along with filiation, from the biological parents to the adoptive parents.
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or through biochemical analysis to measure specific protein output. In a medical setting, genetic testing can be used to diagnose or rule out suspected genetic disorders, predict risks for specific conditions, or gain information that can be used to customize medical treatments based on an individual's genetic makeup. Genetic testing can also be used to determine biological relatives, such as a child's biological parentage through DNA paternity testing, or be used to broadly predict an individual's ancestry. Genetic testing of plants and animals can be used for similar reasons as in humans, to gain information used for selective breeding, or for efforts to boost genetic diversity in endangered populations.
Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable. The tests have been promoted by amateur groups, such as surname study groups or regional genealogical groups, as well as research projects such as the Genographic Project.
Closed adoption is a process by which an infant is adopted by another family, and the record of the biological parent(s) is kept sealed. Often, the biological father is not recorded—even on the original birth certificate. An adoption of an older child who already knows his or her biological parent(s) cannot be made closed or secret. This used to be the most traditional and popular type of adoption, peaking in the decades of the post-World War II Baby Scoop Era. It still exists today, but it exists alongside the practice of open adoption. The sealed records effectively prevent the adoptee and the biological parents from finding, or even knowing anything about each other. However, the emergence of non-profit organizations and private companies to assist individuals with their sealed records has been effective in helping people who want to connect with biological relatives to do so.
A genealogical DNA test is a DNA-based test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or to estimate the ethnic mixture of an individual. Since different testing companies use different ethnic reference groups and different matching algorithms, ethnicity estimates for an individual vary between tests, sometimes dramatically.
In the United States, adoption is the process of creating a legal parent-child relationship between a child and a parent who was not automatically recognized as the child's parent at birth.
Open adoption is a form of adoption in which the biological and adoptive families have access to varying degrees of each other's personal information and have an option of contact. While open adoption is a relatively new phenomenon in the west, it has been a traditional practice in many Asian societies, especially in South Asia, for many centuries. In Hindu society, for example, it is relatively common for a childless couple to adopt the second or later son of the husband's brother when the childless couple has limited hope of producing their own child.
A genogram is a pictorial display of a person's family relationships and medical history. It goes beyond a traditional family tree by allowing the user to visualize hereditary patterns and psychological factors that punctuate relationships. It can be used to identify repetitive patterns of behavior and to recognize hereditary tendencies.
In clinical diagnostic and functional development, special needs refers to individuals who require assistance for disabilities that may be medical, mental, or psychological. Guidelines for clinical diagnosis are given in both the Diagnostic and Statistical Manual of Mental Disorders and the International Classification of Diseases 9th edition. Special needs can range from people with autism, Asperger syndrome, cerebral palsy, Down syndrome, dyslexia, dyscalculia, dyspraxia, dysgraphia, blindness, deafness, ADHD, and cystic fibrosis. They can also include cleft lips and missing limbs. The types of special needs vary in severity, and a student with a special need is classified as being a severe case when the student's IQ is between 20 and 35. These students typically need assistance in school, and have different services provided for them to succeed in a different setting.
Genealogical bewilderment is a term referring to potential identity problems that could be experienced by a child who was either fostered, adopted, or conceived via an assisted reproductive technology procedure such as surrogacy or gamete donation.
The traditional family structure in the United States is considered a family support system involving two married individuals providing care and stability for their biological offspring. However, this two-parent, heterosexual, nuclear family has become less prevalent, and nontraditional family forms have become more common. The family is created at birth and establishes ties across generations. Those generations, the extended family of aunts and uncles, grandparents, and cousins, can hold significant emotional and economic roles for the nuclear family.
In genealogy and in phylogenetic studies of evolutionary biology, antecedents or antecessors are predecessors in a family line. For example, one is the descendant of their grandparents, who are one's antecedents. This term has particular utility in evolutionary coalescent theory, which models the process of genetic drift in reverse time.
The following outline is provided as an overview of and topical guide to adoption:
The International Society of Genetic Genealogy (ISOGG) is an independent non-commercial nonprofit organization of genetic genealogists run by volunteers. It was founded by a group of surname DNA project administrators in 2005 to promote DNA testing for genealogy. It advocates the use of genetics in genealogical research, provides educational resources for genealogists interested in DNA testing, and facilitates networking among genetic genealogists. As of June 2013, it comprises over 8,000 members in 70 countries. As of July 2013, regional meetings are coordinated by 20 volunteer regional coordinators located in the United States, Australia, Brazil, Canada, England, Egypt, Ireland and Russia.
Adoption in the Philippines is a process of granting social, emotional and legal family and kinship membership to an individual from the Philippines, usually a child. It involves a transfer of parental rights and obligations and provides family membership. The Department of Social Welfare and Development (DSWD) defines adoption as a "socio-legal process of giving a permanent family to a child whose parents have voluntarily or involuntarily given up their parental rights."
Elective genetic and genomic testing are DNA tests performed for an individual who does not have an indication for testing. An elective genetic test analyzes selected sites in the human genome while an elective genomic test analyzes the entire human genome. Some elective genetic and genomic tests require a physician to order the test to ensure that individuals understand the risks and benefits of testing as well as the results. Other DNA-based tests, such as a genealogical DNA test do not require a physician's order. Elective testing is generally not paid for by health insurance companies. With the advent of personalized medicine, also called precision medicine, an increasing number of individuals are undertaking elective genetic and genomic testing.
The second-parent adoption or co-parent adoption is a process by which a partner, who is not biologically related to the child, can adopt their partner's biological or adoptive child without terminating the first legal parent's rights. This process is of interest to many couples, as legal parenthood allows the parent's partner to do things such as: make medical decisions, claim dependency, or gain custody in the event of the death of the biological parent.
African American genealogy is a field of genealogy pertaining specifically to the African American population of the United States. African American genealogists who document the families, family histories, and lineages of African Americans are faced with unique challenges owing to the slave practices of the Antebellum South and North. These challenges rise from a range of events, including name changes following the American Civil War, the act of separating families for sale as slaves, lack of issued birth or death records for slaves, etc.
Margaret Press is a forensic genealogist and an author of both true crime and mystery novels. She is also known for co-founding the DNA Doe Project with Colleen M. Fitzpatrick.
