An inbred strain of plants has a mean height of 24 cm. A second strain of
the same species also has a mean height of 24 cm. When these plants are
crossed, the F1 are also 24 cm in height. However, when the F1 plants are
crossed, the F2 plants show a wide range of heights; the greatest number
are similar to the P1 and F1, but approximately 4 of 1000 are only 12 cm
tall and 4 of 1000 are 40 cm tall. What fraction of the F2 plants will be
approximately 28 cm in height? [Assume that each of the alleles involved in
determining increase in plant height contributes the same amount.]
