A recent study from the University of Maryland suggests that we might not even be a hybrid.
In a study, published in the Journal of Personality and Social Psychology, researchers compared participants with DNA profiles that match their own and those from their parents and grandparents.
They also looked at a group of individuals with similar DNA profiles, who all had been adopted by a biological family member.
The study found that only two percent of adoptees had a mix of genetic material from both their parents.
Researchers said the study suggests that the majority of adopters have a mixture of DNA from both parents.
Researchers also examined DNA from a total of 5,542 people who had been tested for the gene mutations known as rs141888.
The researchers say the researchers found that the number of people with this mutation is about one in four.
“The mutation is associated with an increased risk for autism spectrum disorder, schizophrenia, and other developmental disorders, with an additional risk for schizophrenia in the offspring,” the study’s lead author, Rebecca L. McManus, wrote in a news release.
“These mutations are highly common in people with the disorder and are linked to increased risk of suicide, substance abuse, and depression.”
Researchers say there are three main types of genetic variations: autosomal, mitochondrial, and nuclear.
The researchers used data from the U.S. National Health and Nutrition Examination Survey (NHANES) to analyze the DNA of 2,823 people.
They compared those who were tested with DNA samples from adoptee parents, grandparents, siblings, and siblings who were adopted from their biological parents.
They found that 46 percent of the adopteees with DNA from their adopteres had mutations from one of these three types.
“As we all know, there are hundreds of thousands of people living today that share our DNA and yet do not meet our genetic requirements,” McManuses said in the release.
The researchers say they plan to continue to study these people to learn more about the genes that influence their behaviour.
