gene on the heterozygous sex chromosome (W in snakes) is about the only scenario I can think of and if that happened, only females could have the gene. Then there is also things like the desert, which the heterozygous females appear to be infertile. Which obviously makes it physically impossible to make a homozygous. Well maybe you still make one in a test tube? I donno.

But yes in theory every gene should have a homozygous, unless its a W sex-linked gene
