Most people feel as though they look more like their biological mom or biological dad. They may even think they act more like one than the other. And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
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.
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.
Genes are passed from parents to their progeny. Genes from the father are responsible for determining the gender of the baby as a male is responsible for having a Y chromosome. Some of the other traits that a father is likely to pass on are the color of hair, the color of eyes, height, teeth, etc.
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.

Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Fathers have both X and Y chromosomes. So they contribute one Y or one X chromosome to their offspring. Daughters get two X chromosomes, one from Mother and one from Father. So Daughter will inherit X-linked genes from her father as well as her mother.
We inherit a set of 23 chromosomes from our mothers and another set of 23 from our fathers. One of those pairs are the chromosomes that determine the biological sex of a child – girls have an XX pair and boys have an XY pair, with very rare exceptions in certain disorders.
In fact, dad's contributions to their baby boy's genes make up sixty percent of the kiddo's looks. Mom's contributions only influence the other forty percent, which explains a lot in terms of baby boys looking like identical, miniature copies of their daddies!
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.
Female genetic superiority: when it comes to survival, two X chromosomes beat an X and a Y. In his new book 'Better Half', Dr. Sharon Moalem explains the survival advantage that allows women to better overcome biological challenges throughout their lives than men.
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.
Dominant alleles are seen as an uppercase of a letter; for example, B. Recessive alleles are seen as a lower case of a letter; b. In order for a person to show the dominant trait, one of the person's parents must have the dominant trait (which is an uppercase letter).
Boys, on the other hand, only receive a Y chromosome from their father and an X chromosome from their mother.
Contrary to popular belief, there is no scientific evidence that suggests all firstborn daughters necessarily resemble their fathers.
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.
There is currently no human evidence to suggest that girls inherit their mother's body shape and boys their dad's, or vice versa.
Genes that express themselves more
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.
Haemophilia is a sex-linked recessive disease. The defective genes present on the X chromosome only and not on the Y chromosome. As the father always contributes a Y chromosome and never passes an X chromosome to his son, the gene for haemophilia can never be passed from a father to his son.
According to an old notion, first-born children are genetically predisposed to appear more like their father. It was thought that this was done so that the father would accept the child as his and provide for and care for them.
Athletic achievement is influenced by a variety of circumstances, but heredity is a major one. It's not as simple to answer as it might seem if athletic genes originate from mum or dad. Many genes that can influence a person's athletic prowess are contributed by both parents.
As well as the tip of your nose (which is 66% likely to be passed down from a parent), the other most-inherited features were your philtrum (the area directly beneath your nose), your cheekbones, the inner corners of your eyes, and the areas both above and below your lips.
