Contexts: My mom is 4’11 and my dad is 5’6. I grew up to be 6’0, and so did my brother. My sister grew up to be 5’2, which seems more believable and normal.
As far as I know, my grandparents on both ends aren’t any taller than average. How is it that I came out taller than both my parents and what are the chances that my brother also comes out taller too? How does it work and how is height determined?
In: Biology
What is more important to your height then your genes are your diet growing up. People who have grown up with periods of malnutrition end up shorter then those with plenty of food available all the time. And also their kids end up shorter. What you describe with kids taller then their parents and parents taller then their grandparents is the common pattern we see everywhere. There were global issues with food production and distribution both in the 30s and 40s and this continued on throughout the 50s and even into the 60s.
