You would need a black banded male to get the black tort and whites then. It would also depend if the banded male was Baba or BaBa how many your would get. With the black tort female to a black banded male you would potentially get Black tort and white females, black tort females, black banded males, melanistic yellow banded males, black males and melanistic yellow males assuming the male has only the one Ba gene. It also depend what is carried in the background!
