Your hair color, eye color, and skin color are traits which can be from your parents,
grandparents and all the way up to you're ancestors.
Because of the number, size, shape of melanin we have in our body
Melanin is the pigment of our skin.
Human physical traits are controlled by genetics.
The study of physical repercussion of human traits as human mutations from abuse or human interactions.

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.

Human genetic traits are primarily controlled by genes, which are sequences of DNA that code for specific traits. These genes are inherited from our parents and can be influenced by both genetic and environmental factors. The combination of genes we inherit determines our physical characteristics, such as eye color, height, and susceptibility to diseases.

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.
DNA you get them passed down from genes/traits!
DNA you get them passed down from genes/traits!
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.
Traits are controlled by the genes of the parents.

The human is classified a male. Physical traits include male sex organs, but small testes. They are sterile. Can have some breast enlargement and other female characteristics which are common.
The human would be female. They would be sterile and her sex organs will not mature.
