All of the options mentioned can determine a trait of an organism.
- The number of dominant alleles refers to the presence of dominant genes that have the ability to express themselves in the phenotype. Dominant alleles can override the effects of recessive alleles.
- The phenotype refers to the physical characteristics or traits that are expressed by an organism. The expression of genes, both dominant and recessive, contributes to the phenotype.
- The combination of alleles refers to the specific arrangement of genes an organism possesses. This combination can determine the expression of traits.
- The number of copies of a gene can also influence the phenotype. For example, having multiple copies of a gene can result in an increased expression of a specific trait or characteristic.

But I just need one answer
The combination of its alleles determines a trait of an organism.
What statement is accurate about dominant alleles?
they are expressed only when a recessive allele is not present
they result in the trait of shortness in pea plants
they are indicated by lowercase letters
they are expressed whenever present
they are expressed only when a recessive allele is not present
they result in the trait of shortness in pea plants
they are indicated by lowercase letters
they are expressed whenever present
The statement "they are expressed whenever present" is accurate about dominant alleles. Dominant alleles are expressed and their traits are observed regardless of the presence of recessive alleles.
