Desert rose seedlings

Question

I planted desert rose seeds they are growing. But why are two of them are white and not green why ?

Answer 1

This is a phenomenon that happens occasionally when growing from seed, variegated leaves also can germinate.
From my research, the all white seedlings are quite difficult to grow to adult size.
