Does height come from mom or dad?

Height comes from both mom and dad, as it's a complex trait influenced by many genes inherited equally from both parents, along with environmental factors like nutrition and sleep, though some studies suggest slight variations in contribution for sons vs. daughters. You get roughly half your genes from each parent, and these genes, found on chromosomes 1-22 and X, interact to determine growth, with the Y chromosome from dad determining sex but other genes influencing height.

How tall will I be if my mom is 5'3" and my dad is 5'10"?

For a child with a 5'10" dad and 5'3" mom, the estimated adult height (using the Mid-Parental Height method) is around 5'8" for a boy and 5'3.5" for a girl, with a typical range of about 4 inches above or below that estimate, meaning a boy could be 5'4" to 6'0", and a girl 4'11.5" to 5'7.5". Height is genetic but also influenced by nutrition, health, and environment, so it's just a prediction, not a guarantee. 

Who is taller, mom or dad?

Women generally stop growing any taller around the age of 15, whereas men keep going for another three years. For this reason men tend to be taller than women, for a given set of height genes. In a sense, you could say that the Y chromosome is itself one of those height genes.

Can two short parents have a tall child?

Yes, two short parents can absolutely have a tall child due to complex genetics (like inheriting recessive genes from ancestors), environmental factors (nutrition, health), and genetic recombination, meaning height isn't just a simple blend but influenced by multiple genes from a larger family tree. While height is mostly genetic (60-80%), good nutrition and health during growth can help a child reach their full genetic potential, potentially surprising taller than expected. 

Does father or mother determine the size of a baby?

Both mother and father influence a baby's size through genetics and lifestyle, but the mother's factors often have a stronger direct impact on birth weight (diet, weight, health during pregnancy), while the father's genetics (height, his own birth size) also play a significant role, sometimes even more for skeletal size, suggesting a complex interplay of parental genes affecting fetal growth. Paternal factors like BMI might even have surprising effects, sometimes correlating with smaller babies, while maternal health is crucial for regulating growth, highlighting that both parents contribute to fetal development and long-term health. 

Mom vs. Dad: What Did You Inherit?

What is inherited from father only?

From your father, you inherit the Y chromosome (if you're male, determining biological sex) and a mix of other genes on autosomal chromosomes that influence traits like eye color, height, puberty timing, fat distribution, and even health risks (like certain cancers or heart disease), plus unique Y-linked traits (like hair on the ear or webbed toes) passed exclusively father-to-son.
 

What is the 3 6 9 rule for babies?

The "3 6 9 rule for babies" is a simple guideline for common growth spurts and developmental stages, occurring around 3 weeks, 6 weeks, 3 months, 6 months, and 9 months, marked by increased hunger, fussiness, and disrupted sleep as babies rapidly grow and learn new skills. It's a helpful way for parents to anticipate behavioral changes, recognize feeding needs (cluster feeding), and understand developmental leaps, though timing can vary by baby.
 

Which parent does height usually come from?

Both parents' heights contribute to a child's potential height. The genetic inheritance from both sides of the family plays a role, and the interaction between these genes can result in diverse outcomes. It's a common misconception that a child will take after just one parent in terms of height.

What causes a child to be very tall?

Some children may be abnormally tall for their age from an early, rapid development of puberty or from an excess production of the growth hormone by the pituitary gland. These and other more rare conditions can stimulate growth, particularly of the jaw and the long bones of the arms and legs.

Is 7 feet tall for a 12 year old?

How Tall Should a 12-Year-Old Be? We can only speak to national average heights here in North America, whereby a 12-year-old girl would be between 137 cm to 162 cm tall (4-1/2 to 5-1/3 feet). A 12-year-old boy should be between 137 cm to 160 cm tall (4-1/2 to 5-1/4 feet).

Which sibling is usually the tallest?

While controlling for number of younger siblings, we estimate first-born children as 13.5 mm taller than those with one older sibling and 17.4 mm taller than those with two or more ( Figure 2B).

What genes are inherited from mother only?

The genes inherited exclusively from the mother are the tiny set of genes located in your mitochondria (mtDNA), which are passed down through the egg, plus the genes on the X chromosome that she contributes, which influences traits like intelligence potential, and even some factors in aging and focus, though these involve complex interactions. While most nuclear DNA comes from both parents, mtDNA is a unique maternal lineage, affecting energy, aging, and some diseases like blindness or hearing loss.
 

Are boys usually taller than their dad?

Sons are often slightly taller than their fathers, but it's not guaranteed; it depends on genetics (from both parents) and improved nutrition over generations, with average heights increasing globally, but tall fathers tend to have sons who are closer to average height, while shorter fathers have sons who often grow taller than them, though still potentially shorter than the father's actual height due to height regression to the mean.
 

Does ethnicity affect height prediction?

Ethnicity is an important factor determining the height of an individual. Ethnically different populations might respond differently to the same environmental factors and thus the final height in different ethnic groups is different. Height is a polygenic trait with a high degree of heritability.

Do grandparents affect a child's height?

Yes, your grandparents' height definitely affects your potential height because you inherit genes from all four grandparents, each contributing about 25% of your genetic makeup, though height is complex with many genes and environmental factors (nutrition) also playing huge roles, meaning you could be much taller or shorter than your parents by inheriting dominant genes from a tall grandparent or shorter ones from others. 

What foods make kids taller?

Foods high in protein, calcium, vitamin D, magnesium, phosphorus, and vitamin C, such as milk, eggs, leafy greens, fruits, and lean meats, can significantly contribute to your child's height and overall physical development.

Can short parents make a tall child?

It's entirely possible for two short parents to have a tall child, and vice versa.

How can you tell if a child will be tall?

Signs your child might be tall include genetics (tall parents), being long at birth, consistently being taller than peers, rapid growth spurts with increased hunger/sleep, and sometimes bigger feet before height changes, but the best prediction uses parental height via a simple calculation or a doctor's bone age X-ray for a more accurate growth potential. 

Will I be tall if my dad is tall but my mom is short?

You'll likely be somewhere between your tall dad and short mom's heights, but genetics are complex, so you could be taller or shorter, influenced by many genes from both parents and factors like nutrition, potentially landing closer to your dad's height (especially if you're a boy) or averaging out, but you might even exceed the taller parent, say Reddit users. Height is a polygenic trait (many genes) plus environmental factors (nutrition, health). 

Does sleep affect height growth?

Yes, sleep significantly affects height growth because the body releases human growth hormone (HGH) (HGH) primarily during deep sleep, essential for development; chronic sleep deprivation in children and teens can suppress HGH, potentially leading to shorter stature, though genetics and nutrition are the main determinants of adult height. While one bad night won't matter, consistent lack of sufficient, quality rest during developmental years can hinder growth and overall health.
 

Is height 90% genetics?

They knew that about 80 to 90 percent of height is shaped by genetics, with environmental factors playing a smaller role. And by studying family histories, they'd identified hundreds of monogenic traits: single, rare genetic variants that can have large effects on height.

What is the 20 minute rule for babies?

Hold your baby until they're in a deeper sleep. Babies start in 'active sleep' (with faster, uneven breathing) and move into a deeper sleep after about 20 minutes. That's a good time to transfer them into their sleeping place. Many babies don't like being put down into a cot.

Does sleeping more indicate a growth spurt?

Growth spurts typically last a few days and typically lead to increased hunger and fussiness and changes in sleep patterns. Research shows babies may have unexpected increased napping and an increase in overall sleep totals. On the other hand, increased hunger may lead to disrupted sleep (i.e. increased night wakings).

At what age is SIDS no longer a risk?

SIDS is less common after 8 months of age, but parents and caregivers should continue to follow safe sleep practices to reduce the risk of SIDS and other sleep-related causes of infant death until baby's first birthday. More than 90% of all SIDS deaths occur before 6 months of age.
