The combination of its alleles.

but is this true?

Yes, the combination of alleles (different forms of a gene) is what ultimately determines a trait of an organism. This combination of alleles influences the organism's genotype, which in turn affects its phenotype (physical characteristics). Each trait is typically determined by the interaction of multiple alleles.
