In hamsters, crosses between any two dwarf hamsters always produce both large and dwarf progeny in a ratio of about 1:2 (large : dwarf). Crosses between large hamsters only produce large progeny. Moreover, some crosses between black hamsters produce all black progeny, and some crosses between black hamsters produce both black and brown progeny. Assuming that the size and fur color phenotypes segregate independently, what are the expected phenotypes in the F1 of a cross between a dwarf hamster that is pure-breeding for brown fur color and a large hamster that pure-breeding for black fur color
