Could Scientists create a YY... being?

After thinking about what I learned in science class in school years ago, I started to wonder if a YY...being, could be created. Surely it could be created, but has it been? And what was the outcome?

No. The Y chromosomes are missing a lot of genes. That's fine for men, since they have spare copies in their X chromosomes, but if you had YY genes, you wouldn't have them. Some of those genes are going to matter.
