• A trait that appears even if an organism has only one allele for it

• A trait that appears only if an organism has two alleles for it

• It cannot inherit the trait

What does it mean if an organism is heterozygous for a trait?

• It has two identical alleles for a trait

• It has two different alleles for a trait
