While you inherit roughly 50/50 DNA from each parent, studies suggest the father's genes often show more "dominance" or activity in certain traits, especially health-related ones, with paternal DNA potentially influencing aging and some gene expressions more strongly, though the mother provides crucial mitochondrial DNA and potentially more total DNA in males due to the larger X chromosome.
If a gene is dominant, there only has to be one copy present in the pair for it to be expressed. This means that if a parent passes on a dominant gene to their child, the child will most likely express it, regardless of which gene is inherited from the other parent.
“Which parent gives you the most dominant genes?” Except for a few special cases (see below), it doesn't really matter which parent gave you which gene. If a gene version is dominant, it will dominate whether it came from mom or dad. Your chances of getting a dominant trait don't depend on which parent it came from.
Genetically, a person actually carries more of his/her mother's genes than his/her father's. The reason is little organelles that live within cells, the? mitochondria, which are only received from a mother. Mitochondria is the powerhouse of the cell and is inherited from the mother.
Below are some of the genetic traits that are inherited directly from your biological father.
Intelligence genes are situated on the mother's X chromosome. Thus, an intelligent mom has intelligent kids even if their fathers aren't wise. Scientists from the University of Cambridge conducted this study. The 'conditioned genes' behave differently depending on their origin.
We inherit more genes from our maternal side. That's because it's the egg, not the sperm, that hands down all of the mitochondrial DNA. In addition, the W chromosome has more genes.
Mitochondrial DNA
Perhaps the most well-known type of DNA you inherit solely from your mother is mitochondrial DNA (mtDNA). Unlike the DNA in the cell's nucleus (nuclear DNA), which is a combination of both parents' genetic material, you can find mtDNA in the mitochondria – the “powerhouse” of the cell.
The best predictor of a child's height is their parents' height or, more specifically, the mid-parental height. The mid-parental height is calculated by adding the mother's and father's height, adding 13 cm (5 inches) for boys or subtracting 13 cm (5 inches) for girls, and then finally dividing by 2.
Superfecundation is the fertilization of two or more ova from the same menstrual cycle by sperm from the same or different males, whether through separate acts of intercourse or during a single sexual encounter with multiple males. This can potentially result in twin babies that have different biological fathers.
Males inherit slightly more DNA from their mother—about 51%—and 49% from their father. This happens because men inherit their mother's X chromosome, which is larger and carries more genes compared to the smaller Y chromosome inherited from their father.
It is not uncommon for Ancestry Composition Inheritance to report that a son or daughter inherited slightly more or less than 50% from each parent. This is because Ancestry Composition relies on the autosomes (chromosomes 1–22) and the X chromosome(s) to calculate Inheritance.

The most common explanation why you would have more of certain ethnicity than a parent would be that your other parent also had the same ethnicity. For example, if your father were 25% Irish and your mother 75%, you would be about 50% Irish and twice as much as your father.
Can Two Blue-Eyed Parents Have a Brown-Eyed Child? It is possible for two blue-eyed parents to have a brown-eyed child. Blue eye color is recessive while brown eye color is dominant. So, if the gene for brown eye color is present in the parents' DNA, then their child could have brown eyes.
The only difference between men and women is the sex chromosomes and only that and since the Y is the smaller of the two sex chromosomes it means you technically inherit more DNA from your mom if you're a guy.
#1 Baby's Biological Sex
It's one of the physical traits that's 100% determined by paternal genes and/or dads. The Supporting Evidence : While mothers will always pass down their X chromosome (considering it's the only kind they have), fathers will pass down either an X or Y chromosome at random.
Try this little formula for yourself with your parents' heights, and ask your friends and family to do the same. Though it's probable that your real height is close to your predicted height, this isn't always the case. It's entirely possible for two short parents to have a tall child, and vice versa.
Mid-parental method
Another way to estimate your child's adult height is to add together the height of both parents and divide it by two. Then, some methods say to add 5 inches if they're a boy and subtract 5 inches if they're a girl; others say to only add or subtract 2 ½ inches.
Maternal intellectual ability has direct influence on children's intellectual development because it is a genetically based and heritable trait (Kirkpatrick, McGue, Iacono, Miller, & Basu, 2014).
Fathers will always pass their X chromosome to their daughters and their Y chromosome to their sons.
Unlike nuclear DNA, which is inherited from both parents, mitochondrial DNA is usually inherited only from our mothers.
New research shows that daughters, but not sons, appear to inherit a mother's body composition and body mass profile. If you or someone you know is pregnant or planning to become pregnant, talk with a healthcare provider about strategies to reduce excess body fat, and how to control excess weight gain during pregnancy.
Fetal cells also pass through the membrane of the placenta and reach the womb during pregnancy. Male fetal cells have been found in women's blood up to 27 years after delivering a son. Thus, a lady may retain her baby's father's DNA for several decades following childbirth.
