You get hair genes from both parents, inheriting DNA from each, but specific traits like texture, color, and hair loss risk involve different genes, with the X chromosome (from Mom) playing a significant role in male baldness, while numerous other genes from both sides contribute to overall hair characteristics. It's a complex mix, not just one parent's influence.
Hair genes can be inherited from both parents. The genetic contribution for traits like hair color, texture, and other characteristics comes from a combination of genes inherited from both the mother and the father.
Both parents contribute to your hair genetics, with the AR gene from the mother and other influential genes from the father. Hair traits such as balding, color, and greying are polygenic, meaning multiple genes contribute rather than a single source.
Your biological father can pass on physical traits such as your biological sex, eye color, height, puberty timing, fat distribution, dimples, and even risk factors for certain health conditions.
Hair growth rates also vary between hair races. Caucasian hair grows at a rate of about 1.2cm a month and has the greatest density of all three hair types. Blondes have about 146,000 hairs on their heads, black-haired beauties about 110,000 hairs, brunettes 100,000 hairs and redheads roughly 86,000 hairs.
“The ethnicity with the least amount of terminal hair is Asian, whereas people of Hispanic and Middle Eastern descent typically have the most. Other ethnicities fall somewhere in between. So what's normal, hair-wise, for you might not be normal for someone of a different ethnic background.”
1. Harvard University. Harvard University is the global leader in genetics research. Its Share in the topic is almost one-third higher than that of the Max Planck Society, in second.
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.
The nucleus contains genetic info in a combination of 23 pairs of chromosomes that are made from DNA. You inherit one pair from each of your parents. 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.
Fathers will always pass their X chromosome to their daughters and their Y chromosome to their sons.
Studies have identified that the genetic predisposition to Male Pattern Baldness is inherited from both parents, though the influence of genes from the maternal side is particularly significant due to the role of the X chromosome.
Every cell we have descends from a the first human cell, a zygote. And zygote mitochondria comes only from egg cells, never from sperm cells. So every gene that belongs to us from mitochondria is only inherited from our mom's side. So, taking this into account, you could say that we have more mom genes than dad genes.
Curly hair is found across all ethnicities, though its prevalence and type can vary. It is common among people of African descent, who often have tightly coiled hair. Wavy and curly hair types are also prevalent in Middle Eastern, European, South Asian, and Latin American populations due to diverse genetic backgrounds.
Researchers suggest that paternal genes linked to facial structure and bone growth may be more dominant, influencing these traits more strongly. While mothers often pass down softer facial features, both parents contribute to a child's appearance overall.
It can, and often does. One of the most common questions we hear is, "Can baldness skip a generation?" The short answer is yes.
Your brother's unique DNA, being slightly different to yours, explains why brothers the world over can have totally different volumes of hair.
Traits like a specific type of earlobe or finger length can be inherited from your dad. Some quirky traits, like webbed toes, are linked to the Y chromosome. These Y-linked disorders are passed directly from father to son, creating a unique family trait you can trace back through generations.
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.
The eye color of both parents can impact the likelihood of specific eye colors in their offspring. For example, if both parents have brown eyes, it is more likely that their child will also have brown eyes. Ethnicity can also influence eye color inheritance.
However the researchers looked at it, first-borns had, on average, an IQ of 1.5 points higher than second-born siblings, who in turn had a 1.5 higher IQ than third-borns and so on.
Essentially, giftedness is a brain-based difference that impacts development, thinking and learning. It is highly genetic, meaning that while early experiences are influential, gifted people are essentially just born the way they are.
A study of 35 families led by a UCSF Psychiatry researcher showed for the first time that the structure of the brain circuitry known as the corticolimbic system is more likely to be passed down from mothers to daughters than from mothers to sons or from fathers to children of either gender.
The gene family plexins, members of which are mutated in several monogenic neurodevelopmental disorders, was significantly enriched for associations with high IQ.
Skin barrier function is reportedly stronger in darker skin tones (the stratum corneum is the skin barrier). Asian skin is reported to have similarities with Caucasian skin in terms of water loss and has the weakest barrier function.
Drosophila is the Queen of Genetics. It is the most amenable model organism for genetics where one can fine tune gene expression spatially & temporally & ask fundamental questions relevant to us.
