If they are tall or short, then your own height is said to end up somewhere based on the average heights between your two parents. 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.
Which parent does a child get their height from?

How is height passed down genetically?
Height is not solely determined by genetics. Nutrition, connection to quality food and socioeconomic class all influence overall height. Yet, for some, inherited genetic changes result in shorter height. Achondroplasia is one of many forms of dwarfism, occurring due to an inherited change in a person’s genetics.
What type of inheritance is height?
Traits that display a continuous distribution, such as height or skin color, are polygenic. The inheritance of polygenic traits does not show the phenotypic ratios characteristic of Mendelian inheritance, though each of the genes contributing to the trait is inherited as described by Gregor Mendel.

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.
What does a girl inherit from her mother?
Girls receive an X-chromosome from each parent, therefore their X-linked traits will be partially inherited from dad, too. Boys, on the other hand, only receive a Y chromosome from their father and an X chromosome from their mother. That means all of your son’s X-linked genes and traits will come straight from mom.
Which race is the tallest?
The Nilotic peoples of Sudan such as the Shilluk and Dinka have been described as some of the tallest in the world. Dinka Ruweng males investigated by Roberts in 1953–54 were on average 181.3 centimetres (5 ft 11 1⁄2 in) tall, and Shilluk males averaged 182.6 centimetres (6 ft 0 in).
