Scientists estimate that about 80 percent of an individual's height is determined by the DNA sequence variations they have inherited, but which genes these changes are in and what they do to affect height are only partially understood.
A combination of genetics and external factors can affect how tall a child will grow. Health experts believe that 80% of a person's height is genetic. This means the height of biological parents can be an indicator of a child's height, although this is not always a reliable predictor.
Though it's probable that your real height is close to your predicted height, this isn't always the case. It's entirely possible for two short parents to have a tall child, and vice versa. It's just more likely that the child of short people will end up vertically challenged.
Nearly 10,000 common gene variants influence how tall a person becomes. For height, DNA is largely destiny. Studies of identical and fraternal twins suggest up to 80% of variation in height is genetic.

You get your height genes from both sides of your family - and you can end up taller or shorter than either or both of your parents. You never know if some of your ancestors might have contributed genes. My mother was 5'7” and my dad was 6”2”.
For an exceptionally tall man, his son will be around 4 inches (10cm) shorter than him. His son will still be taller than average. A 58-inch-tall (147cm-tall) man will have a 63.5-inch-tall (161cm-tall) son. For an exceptionally short man, his son will be around 5.5 inches (14cm) taller than him.
Just because we do not see a specific ancestral trait does not mean that he/she does not carry it. The more tall ancestors you have determines the likelihood of you being tall, however, if there is even one ancestor that carries the genetics of shortness you have a possibility of ending up short!
Are sons always taller than mothers? No. There are genetics at play and medical conditions that could easily cause a son to be shorter than their 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.
Are children usually taller than their parents? A. The results vary from child to child and family to family, and depend on genes and environmental factors, especially nutrition. Doctors often use a fairly simple formula to predict the adult height of a child based on the heights of the parents.
If a mother and father are the same height, their daughters will be roughly the same height, but their sons will be taller. This is because in order for the mother to be the same height as her husband, she must have more of the other 'tall genes' than him, and these get passed onto her sons.
Most girls stop growing taller by age 14 or 15. In contrast, after their early teenage growth spurt, boys continue gaining height at a gradual pace until around 18. Note that some kids will stop growing earlier and others may keep growing a few years more.
If your baby tops the length charts, you might expect them to tower above their classmates one day. But a long infant won't necessarily become a tall adult—just like short babies don't always turn into small-statured people. In fact, a fetus' size is largely determined by the placenta's health.
Some of the reasons growth development may slow include: Genetics. When a child's parents and grandparents are short, the child may also be short; this is known as familial short stature. Also, the target height is merely an estimate and some children simply don't grow as tall as expected.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Babies and children grow continuously. This is due to changes in the growth plates in the long bones of their arms and legs. As the growth plates make new bone, the long bones get longer, and the child gets taller.
The simplest way to conclude if you're tall or not is to look around you. If you're in the US, compare your own height to the North American average for men, which is 5'9″ (177 cm). If you are 5'10” (178 cm) or taller, you are considered taller than average in North America.
This is about ~2.7 inches. The average phenotypic difference between siblings was about 7.2 centimeters (D). Therefore, to a first approximation the recapitulation of population-wide variation in a continuous quantitative trait within sibling cohorts seems to hold.
What can I do to become taller? Taking good care of yourself — eating well, exercising regularly, and getting plenty of rest — is the best way to stay healthy and help your body reach its natural potential. There's no magic pill for increasing height. In fact, your genes are the major determinant of how tall you'll be.
That's because your height is determined by your genes — the complicated code of instructions that you inherit from your parents. Genes tell your body how to grow and determine lots of things, including how tall you are. But those genes don't make you an exact copy of your mom or dad.
