Only mitochondrial DNA is inherited from the mother alone. It is passed to both sons and daughters through the egg. A few imprinted genes and, in sons, all X-linked genes also come only from the mother. Everything else, including height, eye color and intelligence, comes from both parents.
Traits and genes that come from the mother only:
- Mitochondrial DNA (mtDNA): 37 genes that help your cells produce energy. Passed to sons and daughters, but only daughters pass it on.
- Mitochondrial conditions: for example Leber hereditary optic neuropathy and MELAS syndrome.
- X-linked traits in sons: a son gets his only X chromosome from his mother, so traits like red-green color blindness and hemophilia come through her.
- Maternally imprinted genes: a small group of genes where only the mother’s copy is active, such as UBE3A (linked to Angelman syndrome).
Commonly believed, but not mother-only: intelligence, height, eye color, hair color, skin tone and athletic ability. These come from both parents. Although we have it from both our father and mother, some things are inherited by children from the mother only. These traits inherited from the mother are associated with some particular gene that is passed down from generation solely through the mother’s side. In this article, you will learn what inheriting means, what genes are inherited from a mother, and how much of the person is derived from the mother.
What does inherited trait mean?
Before defining the nature of traits we inherit, let us first consider what inheritance traits really mean. In other words, an inherited trait refers to any character that an offspring possesses from his parents through the genes that are present in their body. These attributes may include physical characteristics, such as hair color, talents, abilities, or even medical preparedness. One gets 50% of genes from each parent, but there are certain characteristics, more often those correlated with specific chromosomes, which are inherited solely from the mother figure.
What genes are inherited from the mother only?
Of all the possible traits inherited from mother, one of the most well-known ones is, of course, mitochondrial DNA. mtDNA is present within the mitochondria (the energy-generating organelles) and is inherited only from the mother. This means that each human has a mitochondrial DNA legacy from their mothers, given that the DNA mtDNA follows the prognosis through the female line.
Even though mtDNA fails to support the scrutiny of source visible features such as eye color, height, and so on, it has a vital role to play in tracing the carrier’s genetic history. It assists in determining lineage and also provides early prediction of genetic diseases such as mitochondrial diseases. There is also evidence that some cognitive and some mental health including vulnerability to mental illness may also be linked to the X-chromosome, which the sons get from the mother.
What physical abilities you inherit from your mom?
One can only receive a combination of physical traits from both parents, but mothers play a certain role in developing a child’s physical and cognitive features. However, in some research works, it has been suggested that intelligence genes are somewhat located on the X-chromosome and, from the mother, are transmitted to both sons and daughters. Other physical traits inherited from the mother may include:
- Hair texture: It might even be by curls; that means if your mother has curly hair, you might have it as well.
- Height: Tallness and shortness you also owe to your mother’s genes.
- Body shape: Often, the mother bequeaths traits to her daughter or to the representation of female thinness, such as how the fat is distributed around the hips or the thighs.

What kinds of traits can be inherited genetically from your parents?
We are usually endowed with many characteristics from both of our parents, and now imagine the possibility of such a mother being a gentleman. While some are obvious, such as the color of the eyes or hair or the skin tone, others are hidden, like risks to health or personality. In addition to the mitochondrial DNA from mothers, here are a few common traits you can inherit from either parent:
- Eye Color: This means that features with dominant alleles, such as brown eyes, may be passed from either parent, but features with recessive alleles, such as blue eyes, may be passed from a parent who herself does not have blue eyes but is a carrier of the gene.
- Height and Build: Your height and body build might be inherited from either your mother, your father, or both parents, but your genetic system will determine your final height and body build.
- Health Conditions: Sometimes, children may inherit health conditions such as heart disease, diabetes, or cancer from either parent.
However, particular traits inherited from your mother may pinpoint features of your individual health and medical past, including frequent diseases caused by mitochondrial DNA or chromosome X.
Conclusion
Our mothers occupy a special and important place when it comes to defining characteristics. From mitochondrial DNA to the X-linked genes, the traits inherited from our mothers influence virtually every aspect of us, phenotypically as well as genetically. These traits will help a person develop information about family history and future health.

FAQ’S
What genetics are inherited by the mother?
A mother passes half of her nuclear DNA to each child, about 50% of their genes, plus all of their mitochondrial DNA. She also gives sons their only X chromosome. Mitochondrial DNA and some imprinted genes come from the mother alone. The rest is shared with the father.
What traits are inherited from father only?
Only the Y chromosome is inherited from the father alone, so its genes pass from father to son only. These include SRY, which triggers male development, and genes for sperm production. Daughters do not get a Y. A few paternally imprinted genes, such as IGF2, are also active only from the father’s copy.
