If you are a man with average height, you can expect your son to be a few inches (centimeters) taller than you.
The genetics of height
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.
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.
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.
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.
It is possible to have a tall child from relatively short parents. Whilst genetics play a major role, other modifiable factors can help increase such a child's height.
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.
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.
Genes from both parents play a role in determining height and growth for both boys and girls. Other factors such as diet, activity level, and the mother's nutrition during pregnancy also affect height.
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.
If the parents are both short heterozygous individuals, they can pass the tall recessive traits to their child. When that happens, the recessive trait becomes activated and such a child will be tall.
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. Mostly, our genes determine how tall we will be.
Both of your parents' height influences yours. The average heights for men and for women are about 5 inches apart - 5'9 and 5'4 in the U.S., respectively. If your mom is shorter compared to other women than your dad is compared to other men, her genes could influence your height to be shorter than your dad's.
In most cases, Boys height measurements for this age group (15 years old) will lie within the range between 154.61 and 184.13 cms. The average height measurement for this age group Boys is 170.14 cms, according to the CDC.
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.
We inherit a set of 23 chromosomes from our mothers and another set of 23 from our fathers. One of those pairs are the chromosomes that determine the biological sex of a child – girls have an XX pair and boys have an XY pair, with very rare exceptions in certain disorders.
And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
According to the Centers for Disease Control and Prevention (CDC) , the average age-adjusted height for American men 20 years old and up is 69.1 inches (175.4 centimeters) during the years 2015 to 2016. That's about 5 feet 9 inches tall. This number comes from data published in December 2018.
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.
A common reason is familial short stature, which means the parents are short. Constitutional delay in growth and puberty is another cause, which means the child is a late bloomer. It's not unusual for someone who has been small all their life to suddenly have a growth spurt late in high school.
