Answer:
It is maternal inheritance (cytoplasmic inheritance) of the gene for petal color.
Explanation:
In the given experiment, the color of the petal is regulated by maternal inheritance. In the first step, the true-breeding pale plant was pollinated by a true-breeding normal plant, therefore, all the F1 was identical in terms of petal color to the female plant (the true breeding pale plant).
In the second step, the F1 pale plants were pollinated by the true breeding normal plant. Again, the petal color in the progeny was determined that the female parent (the F1 pale plant). If true breeding normal plants will be pollinated by true breeding or F1 pale plant, the progeny will exhibit "normal phenotype" for petal color since the female plant has normal phenotype here.

Answer:
The organism at location D is the common ancestor
to organisms at location A, B, and C.
Explanation:
Hi! This is your answer because the organism at location D is at the very beginning of the cladogram thus passing on traits to organisms A,B, and C.
Hope this works for you.
In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.
