Height genes don't change (the answer to your question) but most importantly, they don't mix equally. Whatever you do, seriously, please don't have a son with a 5'1" woman. Regardless of whether the father is 5'7" or 5'11" naturally, the son of a 5'0" or 5'1" woman will almost always never end up taller than 5'5" or 5'6". You would be dooming the poor guy right from the start. It'd be like playing Russian Roulette with 5 bullets chambered.
I need to add that I am only 4”11’
Not true. My son turned 13 this month and he is 5”7’ already. The same height as his dad. I’m sure he still has at least 3 inches before he stops growing.
This is why I say no one should think of height genetics in simple terms like "5'1 genes" or "5'7 genes".
Besides it being a lotto, there are too many factors that affect one final's height.
Everyone has a genetic height potential (with it differing across populations, due to the different genes), nutritional and health height variables, etc. The son of Scandinavian immigrants who were often ill and undernourished throughout their lives will most likely be taller than his parents, granted he suddenly gets perfect healthcare and nutrition. His father could be 5'7 and his mother could be 5'1. He most likely wouldn't be as tall as modern Scandinavians who have had good nutrition and health going on for more generations than himself, but he should, in all likelihood, be taller than even his father.
The reverse is also possible: sometimes people from taller families will have one member, male or female, who's much shorter than the mean for their familial history, despite a history of good health and nutrition going back generations, just because of certain genes/SNPs/etc that appeared back dominantly in this specific person. This is just the lotto at work.
