Oregan-R is a wild-type strain (no mutants)

y is yellow body color, unless your teacher is using it for something
else.

yellow body is a bit tricky until you get used to it.  One of the
yellow alleles produces yellow bristles and yellow wings too.  If
you're using that allele you're lucky.  Put a wildtype fly and a yellow
fly side by side and look at the wings.  Yellow's pretty easy to see in
the wing.  Once you've spotted it you should have no problem.

Hope this helps.
