To resolve the confusion, I'll try to make this make more sense

During Gamete production, crossing over can happen.. So we'll say you've got your two parental chromosomes here.. I'll Use Be for blue eyes and M for mojave. Below are matched chromosomes

---Be------M----
-----------------

Before sperm/egg are produced crossing over can happen so you'd have


-------------M---
---Be------------


Each chromosome would have it's own sperm, so you'd have a sperm with Be recessive/codom gene(I would speculate that it's recessive) And one with whatever other gene/genes gives mojave their flavor.

So we'll say that this animal is paired with a sperm containing a normal mojave set of genes

---Be---------M---
---Be--------------

So now that blue eye is heterozygous, and would be expressed at is in the Blue eyed leucistic, seen below.

---Be---------M---
---Be---------M---

If the other Be chromosome is paired with a normal chromosome you'd get

------------------
---Be------------

I hope this helps.
