You receive 50% of your genes from each of your parents, but the percentages of DNA you received from ancestors at the grandparent level and further back are not necessarily neatly divided in two with each generation.
Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
Genes come in pairs. Each person receives one copy of a gene pair from his mother and one from his father. Even though you get half of your genes from your mother and half from your father, each of your parents contributes to all your traits. For the each trait, there are different versions of a gene.
The percentage of DNA that you share with each grandparent is around 25%. It's true there are some pieces of DNA that are not passed on evenly from all 4 grandparents. But they overall make up a very small percentage of your total DNA.
The nucleus contains genetic info in a combination of 23 pairs of chromosomes that are made from DNA. You inherit one pair from each of your parents. Only one pair, chromosome 23 determines the gender. Genetically, a person actually carries more of his/her mother's genes than his/her father's.
After all, children inherit half of their DNA from each parent: 50 percent from mom (through an egg), and 50 percent from dad (through sperm).
You can't inherit more than half of an ancestor's DNA
You receive 50% of your genes from each of your parents, but the percentages of DNA you received from ancestors at the grandparent level and further back are not necessarily neatly divided in two with each generation.
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.

During the past 20 years, Australian inheritances have added up to almost $1.4 trillion — about $67 billion a year. The average inheritance is about $125,000 and goes to a recipient about 50 years old, who is usually well-established in their career.
Personality Traits
For example, if the father is an independent thinker or risk-taker, it's likely his daughter will have some of those same qualities. Other personality traits such as intelligence, empathy, creativity, and leadership skills can also be inherited from the father.
An estimated 35 to 45 percent of wealth is inherited rather than self-made, according to Kopczuk's review of the literature.
Parents pass on traits or characteristics, such as eye colour and blood type, to their children through their genes. Some health conditions and diseases can be passed on genetically too. Sometimes, one characteristic has many different forms. For example, blood type can be A, B, AB or O.
Physical features such as hair color, hair texture, hairline, skin, and varicose veins are inherited from your mother.
On average, we are just as related to our parents as we are to our siblings--but there can be some slight differences! We share 1/2 of our genetic material with our mother and 1/2 with our father. We also share 1/2 of our DNA, on average, with our brothers and sisters. Identical twins are an exception to this rule.
Your children inherit their eye colors from you and your partner. It's a combination of mom and dad's eye colors – generally, the color is determined by this mix and whether the genes are dominant or recessive. Every child carries two copies of every gene – one comes from mom, and the other comes from dad.
We all know that babies inherit the genetic heritage of their parents in equal parts, half of the genes coming from the mother and the other half from the father. However, a recent study suggests that the father's genes are expressed more and are predominant in the child.
The size and shape of your nose may not be genetically inherited from your parents but evolved, at least in part, in response to the local climate conditions, researchers claim. The nose is one of the most distinctive facial features, which also has the important job of conditioning the air that we breathe.
Males normally have an X and a Y chromosome (XY). A male inherits an X chromosome from his mother and a Y chromosome from his father. The picture above therefore shows the chromosomes of a male as the last pair of chromosomes (XY). Sometimes, there is a change in one copy of a gene which stops it from working properly.
A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons (no male-to-male transmission). X-linked recessive disorders are also caused by variants in genes on the X chromosome.
"Our research, on a much larger sample of babies than Christenfeld and Hill's, shows that some babies resemble their father more, some babies resemble their mother more, and most babies resemble both parents to about the same extent," says Paola Bressan, a psychologist at the University of Padova in Italy who co- ...
The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. So, half the baby's DNA comes from the mother and half comes from the father.
Sometimes children end up looking exactly like one parent, or even closely mirroring a sibling, and sometimes they don't resemble anyone in the family. It's all entirely possible. Kids share 50% of their DNA with each of their parents and siblings, so there's plenty of room for variation.
With each generation, your DNA divides. So, for a 1% DNA result, you would be looking at around seven generations.
