The plant Chloroplastia centruniversiae looks like in two forms in the woods individuals encompass all green or all white leaves. The white leaf form lives for just three days as it can’t photosynthesize. All C. centruniversiae seeds germinate, produce leaves in 1 day, and one day later are flowering; therefore white and green leafed individuals can cross and produce the F1.
Chlorophyll biosynthesis is dependent on the expression of the C gene. The X gene encodes a transcription factor needed for the activation of the C gene. You cross a true breeding white C. Centruniversiae with true breeding green C. Centruniversiae and all of their F1 are green. You then cross any two of such F1 and find out that of the 320 F2, 180 are green and 140 are white.
Describe such results and point out the genotypes of all the individuals explained in this problem.
