Albinism (t) is recessive to normal coloration (T) in tigers and polydactyly (having extra digits- p) is recessive to having a normal number of digits (P). If an albino tiger with polydactyly is crossed with a tiger that is TTPp, how many of their offspring would be expected to have normal coloration AND a normal number of digits (assume a total of 16 offspring are produced)?
