Traits that are controlled a multiple gene loci. Polygenic traits.
This human would be female. There are no unusual physical features. They might be slightly taller than average. They are also put at risk for learning disabilities.

What are human genetic traits controlled by
polygenic inheritance
there are 42 chromosomes in the human body
Polygenic Inheritance
The study of physical repercussion of human traits as human mutations from abuse or human interactions.
