Crossing two true breeding parents with opposite parents is the key:
Assume W is straight wing and w is curly.
Then you are crossing WW with ww
This will result in ALL Ww as offspring - so all straight offspring
If you then cross Ww x Ww you end up with a mix of
WW (1), Ww (2) and ww (1) - so a mix of straight and curly
Answer:
P generation has straight wings and curly wings
F1 has all straight wings
F2 has straight wings and curly wings
All planets have these same layers (From deepest to shallowest, inner core then the outer core, then the mantle, and lastly the crust. A good example is the Earth) that is shown in the diagram, even the sun has all the layers I just listed.
But, some planets I can think of are Mars, Venus, Moon, and the Earth of course.
Layer C. sounds like it could also represent Layer D, since they are so close.
P. S. I did my best to try to answer this.
