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.
Genes aren't the sole predictor of a person's height. In some instances, a child might be much taller than their parents and other relatives. Or, perhaps, they may be much shorter. Such key differences may be explained by other factors outside of your genes that contribute to height.
Maternal height influences offspring linear growth over the growing period. These influences likely include genetic and non-genetic factors, including nutrition-related intergenerational influences on growth that prevent the attainment of genetic height potential in low- and middle-income countries.
However, this has raised concerns in the minds of several individuals. This includes people who may be described as short and those who may have wondered if it were possible. Just as simple as the question is, so is its answer. Yes, short parents can have tall children.
If you are a man with average height, you can expect your son to be a few inches (centimeters) taller than you.
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.

Changes in Boys
They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
Genetic changes happen randomly. There is nothing a parent could do before or during pregnancy to prevent this change from happening. A genetic counselor can help determine the chances of having a child with dwarfism. Depending on the type of dwarfism, two average-height parents can have a child with short stature.
Chances are you'll be around the same height as your parents. If one parent is tall and one short, then you're likely to end up somewhere in between. But you could be taller or shorter, too.
It's typically considered a medical issue if they're smaller than 95 percent of children their age, and their rate of growth is slow. A growth delay may also be diagnosed in a child whose height is in the normal range, but whose rate of growth has slowed.
A family history of short stature
If parents or other family members have short stature, it's common for a child to grow at a slower rate than their peers. Delayed growth due to family history isn't an indication of an underlying problem. The child may be shorter than average simply because of genetics.
A short child is defined as any child whose height is less than the 3rd percentile for his or her cohort. A quick check with your doctor will let you know if your child's growth and height are acceptable. It is important that you track your child's growth (both height and weight) regularly.
He keeps asking if there's anything he can do to become taller. Taking care of himself — eating well, exercising regularly, and getting plenty of rest — is the best way for your son to help his body reach its natural potential. No pill, formula, or nutritional supplement can increase someone's height.
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.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
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.
Growth charts show that majority of guys grow just a little after the ages of 18. In rare cases, some people may hit puberty in their late teens and continue to grow into their early twenties. The reason most guys stop growing at this age is because their growth plates fuse shortly after puberty.
it's a myth . A boy inherits height about equally from both mother and father. Statistically, the average adult height of a boy will be the average of the Father's height and the Mother's Height + 5 inches. So, the average boy will be taller than his father if his mother is less than 5 inches shorter than the father.
Tallness is a recessive trait, short stature is dominant. This means, if two tall people mate they will likely have very tall children. But if a tall person and a short person mate, the short person's short gene will win out over the tall gene (unless the short person has a hidden gene for tallness.)
So 5'11½ boy or 5'1½” girl. This is the norm but your final height is totally dependent on your genetic makeup. These Gene's are inherited from Mom & Dad primarily but traits can also come from Grandparents.
The son has HALF the genes of the father. The mother contributes the other half. Each son will inherit a different set of the father's genes, and a different set of the mother's genes. Therefore, every child's adult height will be different.
“Children who are short because their parents are short (familial short stature) or due to no obvious underlying cause (idiopathic short stature) usually grow at a normal rate for their age, or a slightly slower rate, and they track along a centile line on the growth chart,” says professor Dattani.
