A pure-breeding strain of squash that produced disk-shaped fruits was crossed with a pure breeding strain having long fruits. The F1 had disk fruits, but the F2 showed a new phenotype, sphere, and was composed of the following proportions
Disk 384
Sphere 96
Long 32

A snapdragon plant that bred true for white petals was crossed to a plant that bred true for purple petals, and all the F1 had white petals. The F1 was selfed. Among the F2, three phenotypes were observed in the following numbers
white 240
solid-purple 61
spotted-purple 19
