In a certain type of waterfowl, a single pair of alleles for one gene controls the color of feathers. Three colors are observed, blue, black, and splashed white (a silver color). Crosses among these three types yield the following results: PARENTS PROGENY
Black x blue Blue and black, 1:1
Black x splashed white Blue
Blue x splashed white Blue and splashed white, 1:1
Black x black Black
Splashed white x splashed white Splashed white

1) What progeny would result from blue x blue

2) What mode of inheritance does this represent?
