Polygenic Inheritance
When a trait is being controlled by many genes than such genes are called polygenes and inheritance of such genes is called Polygenic Inheritance.
Certain traits which are controlled by polygenes are-Body height,body weight, body colour etc.
Skin cells are melanocytes are they are secreting a pigment called melanin pigment.Skin colours are due to the melanin.Genes which are responsible for melanin secretion are controlled by polygenes as described in the video.
Skin colour is controlled by AABB and aabb polygenes.Let us study about the various genotype and phenotypes for the inheritance of Body colour.
AABB=Black
AABb/AaBB=Dark
AAbb/aaBB/AaBb=medium
Aabb/=light
aabb=white etc.
