Suppose that two different groups of schmoos (an imaginary animal) live in geographically separated locations and rarely interbreed. On one occasion, a big-footed white-haired schmoo does mate with a small-footed brown-haird scheme. Six offspring result: two big-footed schmoos with light brown hair and four small-footed schmoos with light brown hair. Which statement about the inheritance of hair color in schemes is most likely correct?
