Question
In a natural population of annual plants, a single plant is
found that is sickly looking and has yellowish leaves. The
plant is dug up and brought back to the laboratory.
Photosynthesis rates are found to be very low. Pollen
from a normal dark-green-leaved plant is used to fertilize
emasculated flowers of the yellowish plant. A hundred
seeds result, of which only 60 germinate. All the resulting
plants are sickly yellow in appearance.
a. Propose a genetic explanation for the inheritance
pattern.
b. Suggest a simple test for your model.
c. Account for the reduced photosynthesis, sickliness,
and yellowish appearance
