It seems like there's a slight error in the question. You're likely asking about an organism that has an allele for brown eyes and an allele for blue eyes.

Here's why this is important:

* Alleles: Alleles are different versions of the same gene. In this case, the gene determines eye color.

* Brown and Blue: The "brown eyes" and "blue eyes" are the traits (phenotypes) resulting from different alleles of the eye color gene.

So, to answer your question:

An organism that has an allele for brown eyes and an allele for blue eyes is considered heterozygous for eye color. This means it has two different alleles for the same gene. The actual eye color of the organism will depend on whether brown eye color is dominant or recessive:

* If brown eye color is dominant: The organism will have brown eyes.

* If brown eye color is recessive: The organism will have blue eyes.

Let me know if you'd like more explanation about dominant and recessive alleles!
