Can a Genotype have more then 2 genes associated with it

I know every genotype is made up of 2 genes from the mother and father but are these 2 genes fixed for every genotype? For example if hair color were determined by only one genotype (i don't think it is but just example) then all the colors would be represented by a gene and you could have many different genotypes like brown/red Black/brown ect. Therefore the genotype would have more then 2 genes associated with it (it would have all the colors). Does this happen or is every phenotype like this just a combination of several genotypes.

you're confusing genes with alleles, a gene is a sequence of DNA, so if say GATTACCA makes hair red, then you would see this gene in all redheads.



Also, not all genotypes are sex-dependent, autosomal based traits can come entirely from either parent.

A genotype is a representation of a gene but Aa wouldn't be the same gene sequence as aa or AA

you can

Yes. For example, eye color.
