How do you test for chimerism?

Are all calicos chimeras?
Some male calico or tortoiseshell cats may be chimeras, which result from fusion in early development of two (fraternal twin) embryos with different color genotypes; these torties can pass only one color to their offspring, not both, according to which of the two original embryos its testes are descended from.
What Colour cats make GREY kittens?
The dilution genes can lighten the dominant colours of orange and black genes to a soft cream and grey (blue) coat. This creates a pattern of tortoiseshell. Black and white cats can possibly produce a litter of grey cats!
