Define Genetics The plant Chloroplastia centruniversiae seems in two forms in the woods individuals has all green or all white leaves. The white leaf form lives for merely three days as it cannot photosynthesize. All C. centruniversiae seeds germinate produce leaves within 1 day and one day later are flowering thus white as well as green leafed individuals can cross and produce F1.

Chlorophyll biosynthesis is reliant upon the expression of the C gene. The X gene encodes a transcription factor obligatory for the activation of the C gene. You cross a true breeding white C. centruniversiae with a true breeding green C. centruniversiae also all of their F1 are green. You then cross any two of these F1 as well as find that of the 320 F2, 180 are green, and 140 are white.

Please describe these results and indicate the genotypes of all the individuals described in this problem.
