>Sperm fertilizes an egg, both cells carry the fatal gene and the zygote, or embryo or what ever stage it reaches stops development.



This would still produce a slug or dead embryo. Which would depend on how early the embryo dies. Do arabesque x arabesque produce a higher number of slugs/dead embryos than might be expected? That's the next question to ask. If the answer to that question is no, then the most likely explanation is that arabesque is just a Mendelian dominant mutant gene, and nobody has done the breeding tests needed to find a homozygous arabesque.
