The other has yellow leaves. The F1 have light green leaves.
Five hundred progeny from F1 × F1 crosses are
analyzed. Their leaves show continuous variation in color, but none has
dark green or yellow leaves. What do these data suggest about the number
of genes determining this trait?
There are more than 4 genes that determine this trait.
