Is gneiss metamorphic?
A gneiss is a metamorphic rock. Metamorphic rocks are created by the alteration of rocks by heat and pressure. Therefore, a gneiss may be created from an igneous rock in which case it would be called an orthogneiss.
Does gneiss have fossils?
No, it's an igneous rock, made from cooling and consequently solidification of a magma. Animals (or any other organism) capable of leaving behind a fossil can not survive and do not live in a magma. Fossils can be found in sedimentary rocks or in metamorphic rocks (if the protolith, the original rock, was sedimentary). In metamorphic rocks, fossils are generally intensely deformed and hence difficult to recognise/identify.
In which type of rock are fossils least likely to occur?
Fossils would not likely be found in rock other than limestone, sandstone, and shale, or rock such as marble that has morphed from these sedimentary rocks. Fossils can basically be find in most Sedimentary rocks, but not in Igneous rocks because they are formed in volcanoes.

What is gneiss streak?
Gneiss does not have a streak because it is a metamorphic rock composed of interlocking minerals with no cleavage. The streak test is typically used to determine the color of the powdered form of a mineral when rubbed against a streak plate, but this is not applicable to gneiss.
