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.
Here's how that breaks down by gender: Girls receive an X-chromosome from each parent, therefore their X-linked traits will be partially inherited from dad, too. Boys, on the other hand, only receive a Y chromosome from their father and an X chromosome from their mother.
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.

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.
The study, published in the journal Age and Ageing, also found that if the father lived to 90, it did not correlate to increased longevity and health in daughters. However, if both the mother and father lived to 90, the likelihood of the daughter achieving longevity and healthy aging jumped to 38%, researchers said.
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.
Good gene indicators are hypothesized to include masculinity, physical attractiveness, muscularity, symmetry, intelligence, and “confrontativeness” (Gangestad, Garver-Apgar, and Simpson, 2007).
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.
First off, each child will pretty much get the same number of genes from dad. Boys and girls will get a slightly different set, but these genes won't affect the sort of traits you are talking about. And all the sons will all get the same number of dad's genes. And the same goes for all the daughters.
There is currently no human evidence to suggest that girls inherit their mother's body shape and boys their dad's, or vice versa.
Females undergo the process of oogenesis producing oogonia. Females transfer 22 + X chromosomes to their sperm which combines with 22 + Y or 22+X chromosomes of the sperm, producing a zygote. Thus offspring inherits 23 (22+X) chromosomes from its mother.
An acquired trait is defined as a characteristic or trait that produces a phenotype that is a result of environmental influence. Acquired traits are not coded in the DNA of an individual and therefore most scientists believe they cannot be passed down to offspring during reproduction.
Babies inherit multiple pairs of genes from each parent that play a role in appearance. These genes determine hair color as well as eye color and complexion. And although scientists have yet to determine how many genes ultimately determine the exact color of a child's hair, they do understand how the process works.
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.
Each son receives DNA for his Y chromosome from his father. This DNA is not mixed with that of the mother, and it is identical to that of the father, unless a mutation occurs. It has been estimated that a mutation occurs about once every 500 generations, or every 15,000 years, give or take a few millennia.
Asian-Americans top the list at 86.5 years, with Latinos following closely behind at 82.8 years. Third of the five groups are Caucasians, with an average life expectancy of about 78.9 years, followed by Native Americans at 76.9 years. The final group, African Americans, has a life expectancy of 74.6 years.
Parental longevity is one of the most important predictors of survival to age 100 for both men and women.
Among the "Big Five" personality traits, conscientiousness is especially predictive of living a longer life. The trait has also been linked to health-related behaviors such as smoking and sleep, which may help explain its link to longevity.
Genetics and Eye Color
You inherit one from the mother and one from the father. If the two alleles of a specific gene are different (heterozygous), the trait that is dominant is expressed (shown). The trait that is hidden is called recessive. Brown eye color is a dominant trait and blue eye color is a recessive trait.
Examining 3D face models of nearly 1,000 female twins, researchers have found that the shapes of the end of the nose, the area above and below the lips, cheekbones and the inner corner of the eye are highly influenced by genetics. “The notion that our genes control our face is self-evident.
A face judged as dominant typically features small eyes, low brows, large chin, a more angular face and a low forehead (see also Keating, 1985; Lorenz, 1943). Studies of sexual dimorphism (e.g., Penton-Voak et al., 2001) reveal that males have a bigger jaw, and a more prominent brow ridge and cheekbones.
