What is the expected outcome when an organism has two recessive alleles?

When an organism has two recessive alleles for a particular trait, it displays a recessive phenotype. This occurs because recessive alleles only manifest their traits in the absence of dominant alleles. In a homozygous recessive condition, where both alleles are recessive, the traits associated with these alleles are expressed. For example, in pea plants, if the allele for white flowers is recessive to the allele for purple flowers, a plant with two alleles for white flowers will display white flowers.

The other options describe scenarios that do not pertain to the expression of traits associated with homozygous recessive alleles. Dominant traits can only be expressed if at least one dominant allele is present, while the notion of survival is not directly tied to the presence of recessive alleles; many organisms with recessive traits thrive in their environments. Incomplete dominance refers to a genetic scenario where a heterozygous phenotype is intermediate between the two homozygous phenotypes, which does not apply when discussing homozygous recessive alleles.
