Four o'clock plants can have green leaves, white leaves, or variegated leaves (leaves with areas of white and areas of green). The white regions of the leaves lack functioning chloroplasts. The transmission of leaf color in four o'clock plants demonstrates organelle inheritance. In this problem, you will explore this inheritance pattern. Which of the following crosses between four o'clock plants could produce progeny plants with green leaves? 1. G variegated (female) x variegated (male)
2. G green (female) x white (male)
3. G white (female) x green (male)
4. G white (female) x variegated (male)
5. Gvariegated (female) x white (male)
