In bell peppers, green coloration (G) is dominant to yellow (g) and round shape (R) to dominant to square (r). What percentage of the offspring would be expected to have yellow coloration and round shape if the following plants are crossed: Ggrr x GgRr?

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)?
