This would be known as epistasis because one gene blocks another from expressing itself. Epistasis could also be the interaction between genes.
it is called multiple allele
Phenotypes
what do we call factors that control traits
A very simple way to understand the two is this: phenotype is what you see and genotype is what genes are there. Phenotypes are expressed genes and genotypes include recessive genes that are not seen.
Genes are the cause ... in all cases.
Alleles
Phenotypes are the characteristics of the genes that are most dominant, and can represent themselves. Species have many different genes for example, you dont have the exact same genes as your best friend, and thus, producing different phenotypes which is why you look different... However, you do have may similar genes that make you part of that species.

Phenotypes
This is because phenotypes are the physical appearance. If you had brown hair and so did I, our phenotypes, would still be different.
what do we call factors that control traits
The outward expression of genetic traits are called phenotypes. Phenotypes expression include recessive and dominant genes such as eye and hair color.
Chromosome alterations have variations in phenotypes( the outward expression of genes).
different form of genes are called allele
Polygenic means many genes are influencing one trait. So, the inheritance of this gives you are all sorts of combination of genes that are expressed in various phenotypes. As example think of the different heights of siblings. There are 5 to 7 genes that influence height and in the same relative environment of siblings you get many combinations of those genes which express themselves in different height same sex siblings.
