Then where did Khoa's tall genetics come from? Asians tend to be short, his dad's short, his mom's short.
2 inches taller than the norm like his younger sister Moolan, I can understand. But Khoa is like 6 inches taller than what's he's supposed to be, where did his genetics come from?
Tallness could go back generations as a recessive gene and just show up in K without showing in anyone else. Each trait we have comes from genes. We get one from each parent. Sometimes they can be the same gene given, like two genes for shortness. Sometimes theres a dominant and recessive for example there’s a gene for tall and a gene for short. If it’s recessive gene, two of them need to show up to manifest physically. With K, his parents, grandparents, great great and so on could all have a “short gene” as a dominant trait and “tall” as a recessive. His brother and sister could have both dominant traits for being short, or one recessive and one dominant. K probably has two recessive traits for tall to show, while his siblings have only one recessive trait for tall or both dominant short
J&L will get one of those genes. It’ll depend on what Keene has for the boys.
This is an extremely simplified version (what I remember from high school) as genetics are complicated but hopefully helpful
TLDR; it’s the same as siblings having different hair/eye colors.
He hit a growth spurt as a teen, like most.
