      Which cross can you expect a phenotypic ratio of 3:1 in the F2 generation?

      a. monohybrid cross
      b. dihybrid cross
      c. test cross
      d. none of these

      The F2 generation means the grandchildren. I’m a bit confused on how the cross of the grandparents relates to the grandchildren.
