Leaves Showing Mixed Inheritance
This is a crossbred seedling, descended from purple-leaved and green-leaved ancestors. The segregation of colors in the second generation has been referred to, and is illustrated here in a very interesting way. Most specimens have leaves that are all green or all purple; but here and there one mixes the colors, in a way that has peculiar interest for the student of heredity.
