Physical features. Physical features such as hair color, hair texture, hairline, skin, and varicose veins are inherited from your mother.
Our mitochondrial DNA accounts for a small portion of our total DNA. It contains just 37 of the 20,000 to 25,000 protein-coding genes in our body. But it is notably distinct from DNA in the nucleus. Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Studies suggest that while your genes may determine up to 80 percent of your weight and body shape, environment and personal choice still play a significant role. So even if you're a dead ringer for your mother in old family photos, it doesn't mean you'll enter middle age with the same body.
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.
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. The reason is little organelles that live within cells, the? mitochondria, which are only received from a mother.
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.
Mom gives us 50 percent of our DNA and our dad fills in the other half. But only the students who were really paying attention are likely to recall that not all genes are expressed equally. In many mammals, the scales seem to be tipped toward fathers, whose genes often win the war underway in the womb.
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.
Contrary to popular belief, there is no scientific evidence that suggests all firstborn daughters necessarily resemble their fathers.
Contrary to your impression, at birth, girls look more like their mom than their dad. It is only from the age of one year that they would start to resemble their dad. There are several hypotheses to explain this phenomenon. The first would be related to evolution.
“Firstborn children can be goal-oriented, outspoken, stubborn, independent, and perfectionistic,” Smelser says, and when you look at the way firstborns are nurtured, it starts to make sense why. “These traits are often reinforced by parents through their interactions with the child,” she says.
By Yang Hu, Lancaster University. Have you heard of "eldest daughter syndrome"? It's the emotional burden eldest daughters tend to take on (and are encouraged to take on) in many families from a young age.
Winning by a Nose
Two large-nosed parents are likely to produce a large-nosed baby, and two small-nosed parents to produce a small-nosed baby. However, when a large-nosed father produces a child through a small-nosed mother, the baby can have a medium-sized nose, due to incomplete dominance.
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.
A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons (no male-to-male transmission). A condition is considered Y-linked if the altered gene that causes the disorder is located on the Y chromosome, one of the two sex chromosomes in each of a male's cells.
They found your nose is the part you're most likely to inherit from your parents, and more specifically the tip of your nose is about 66 per cent likely to have been passed down through your family.

Physical features such as hair color, hair texture, hairline, skin, and varicose veins are inherited from your mother.
Your nose, like it or not, is the part of your face most influenced by your genes. Perhaps not surprisingly, areas like the cheeks, which are highly influenced by lifestyle factors like diet, showed the fewest genetic associations. The ways that these genes influence facial shape was not at all uniform.
The psychologist Alfred Adler developed the family order theory, which says that the order in which a child is born shapes their development and personality. The oldest child is seen as the leader, and the child who may experience a stricter upbringing compared to their other siblings.
There's an old theory that says first-born babies were genetically predispositioned to look more like their father. It was believed this was so the father accepted the child was his and would provide and care for them.
Although there was no linear association between parental age and offspring sex, there was some evidence that the very oldest mothers (over 40) were more likely to have daughters. Pregnancy complications are more common in older mothers30, and are more likely to be fatal for male than for female foetuses31,32.
Mothers tend to always see the baby's father in their newborn, and fathers tend to agree – especially with firstborns. It's the outsiders, the extended family and friends who see otherwise. I believe that this evolutionary theory is still very much true, especially with firstborns.
First borns (fb's) are unique in a family system. They are the only children who have their parents exclusive focus, time and energy. These children have the unobstructed resource of parental attention. However, parent's attention is both on the child and that child's environment.
Parents expect their firstborn to be the one to carry on the family name and legacy. Firstborns are expected to not only perform well in school but also at home. They are often expected to be nothing short of excellent in all they do, and on top of that, they are expected to be responsible.
A recent study has concluded that attractive couples are 26% more likely to have a girl as their first child as compared to less-attractive couples.
