Difference between multiple alleles and polygenic inheritance

Multiple alleles vs polygenic inheritance - This lecture explains about the difference between multiple alleles and polygenic inheritance. Alleles refer to different versions of the same gene. So a single gene can have multiple alleles. For example in fruit flies there is a single gene that controls eye color, and the eye color of the fly depends on the alleles they have for that gene (since they have two copies of every gene, being diploid).
A polygenic trait refers to any inheritable trait that is controlled by multiple genes, and each of these genes can have multiple alleles. For example, eye color in humans is a polygenic trait. There are at least three different genes, each with multiple alleles, that determine eye color in humans. Polygenic traits don't follow patterns of mendelian inheritance.
So in summation the difference is multiple alleles refers to different versions of one gene and polygenic traits refers to a single trait which is controlled by multiple genes (each with multiple alleles).

    Three alleles are present among whole population but at any one time in every individual only two alleles Are present. For example a person may have allele A on one chromosome and allele O on anther chromosome of a pair and will have blood group A. Another person may have Allele A and Allele B and so on. Shomu has not talked about allele O the third allele for blood group phenotype. He is talking about only two alleles and calling it multiple alleles. Multiple allele phenomenon is used when a gene has more than two alleles.

My doubt is Sir AABBCC leads to Whitest or Dark Skin colour??
