A new study has found that the differences between your own and your parents’ DNA may be due to their shared ancestry, rather than their physical traits.
The study, published in the journal Science Advances, is the first to suggest that there may be more genetic variation in people than previously thought.
And the findings have the potential to affect everything from our own lives to our relationship with our parents.
“It is very important to understand that the genetic differences between siblings are not just the differences that are there between the parents but also between siblings,” says Dr. Najam Shah, lead author of the study and a geneticist at Harvard Medical School.
“Our work has shown that the amount of variation in genes that exist between parents is much greater than the differences in genetic variation between children.”
The study focused on the X chromosome, the gene that controls hair color and eye color.
Researchers found that genetic differences in the X have increased over time.
People who are more likely to have X-linked genes are more often seen as Asian and white, which is consistent with the findings of other studies showing differences in genetics between different ethnic groups.
“Our findings confirm what previous research has shown about the role of genetic variation on physical characteristics and may be relevant for people in our own community,” Shah says.
As a child, your genes may be passed down to you.
“When we are born, your mother passes on her genes to you, so that you inherit her genes,” says Shah.
When we’re older, our genetic information may be transmitted to our children, who may inherit it too.
So it may be that, like your parents, your siblings will have more genetic differences than people born in different parts of the world.
That could mean that your genetic makeup is more similar to your parents than people who live in different regions of the country.
The study looked at a sample of more than 2,500 pairs of twins and triplets born in the United States and Japan between the years 1991 and 2000.
The researchers found that people born to white, Asian and American parents tended to have more similar DNA than people of other races.
But people born with mixed ancestry were more likely than their own siblings to have similar DNA to their parents, but more likely not to have shared DNA with either of their parents.
There was a difference in the number of shared DNA segments between people of different ethnicities, but the researchers didn’t find any differences between people born from the same ethnicity.
One of the main differences between the different groups was the amount and type of shared ancestry.
The researchers also found that there was more variation in the DNA of siblings than between siblings.
“When the researchers examined the DNA in siblings of mixed ancestry, they found that those who were closer in ancestry to their siblings were significantly more likely, on average, to have an X chromosome than those who had an X or a Y chromosome,” Shah said.
They found that a person who shares DNA with a sibling was likely to carry a mix of X and Y DNA that is also found in a person’s parents.
So, while it may not be easy to spot genetic differences, the fact that your siblings have similar genes and may share the same DNA suggests that there could be more differences between you and your parent than previously realized.
While genetic differences can’t be used to tell you who you are or who your parent is, they can give clues to how your DNA may relate to the characteristics of your genes.
It could also help determine the extent of your family history of genetic disorders, and the chances of developing those illnesses later in life.
“I think that there is a lot of potential for identifying genetic differences among different populations,” Shah added.
