My bro's final height?

Question

my bro is 5 and he is 3'8 my mom is 5'2 and dad is 6'0 what is my bro final height .....

Answer 1

Most likely 5"7-6"0

Answer 2

He will probably be something around 5'10 - 6'2. Both your mom and dad are close to normal height.

Answer 3

Likely the high side of five feet.  

It's all genetics, and the males are going to lean toward the male chromosome (dad's) tendencies for weight, height and build.

There's always exceptions, and a few inches either way won' t be unusual.
