If you are a man with average height, you can expect your son to be a few inches (centimeters) taller than you. This is because the regression line and the SD line both coincide at the average heights. For instance, a father with an average height of 67.7 inches (172cm) will have a 68.7-inch-tall (175cm-tall) son.
Here is a good way to estimate this based on mom and dad's adult height. For Boys: Add 5 inches to mom's height and average this with dad's. Ex: if mom is 5'4” you would add 5 inches to make 5'9” and then average with dad's height of 5'11” and your little boy's predicted genetic height is 5'10”
The mother's genes also come into play, of course; a child can inherit height genes from either parents. If she is 5ft 4 or 5, a male equivalent for her height might be around 5ft 10–6ft. So if the father is 5ft 7 and the mother 5ft 5, if the son gets her height genes, he will be taller than his father.
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.
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.
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.
However, several formulas can provide a reasonable guess for child growth. Here's a popular example: Add the mother's height to the father's height in either inches or centimeters. Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls.
Because boys have the sex chromosomes XY, they must inherit their Y chromosome from their father. This means they inherit all the genes on this chromosome, including things like sperm production and other exclusively male traits.
Since body size (height and weight) is a highly heritable trait which increases male (but not female) reproductive success, the paper hypothesizes that bigger and taller parents have more sons.
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.
Dad's genes play a significant role in promoting growth. The Supporting Evidence: The insulin-like growth factor (IGF protein) is strongly expressed by paternal genes. This genetic trait is also responsible for promoting growth.
Nope. 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”.
As expected, taller and bigger parents have higher offspring sex ratios than is expected, while shorter and smaller parents have lower offspring sex ratios (Kanazawa, 2005) .
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.
It's possible but unlikely. If your a boy with short mom and tall dad. The son will most likely be the dad's height if not a couple inches taller since many sons are taller than both parents. If it's a daughter then the prediction will usually be averaged and closer to the father's height.
We inherit more genes from our maternal side. That's because it's the egg, not the sperm, that hands down all of the mitochondrial DNA. In addition, the W chromosome has more genes.
If you are a man with average height, you can expect your son to be a few inches (centimeters) taller than you. This is because the regression line and the SD line both coincide at the average heights. For instance, a father with an average height of 67.7 inches (172cm) will have a 68.7-inch-tall (175cm-tall) son.
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.
The height value range of 13-year- old males is distributed with the range of 27% from 165 to 170 cm and with a 22% cover range from 160 to 165 cm height.
A major growth spurt happens at the time of puberty, usually between 8 to 13 years of age in girls and 10 to 15 years in boys. Puberty lasts about 2 to 5 years.
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).
