Question
In triffid plants, the color trait and the spikiness trait are controled by two loci that assort independently. A true-breeding smooth green strain of triffids is crossed to a true-breeding spiky orange strain of triffids.
All of the F1 are spiky green.
The geneticist then performs two additional crosses:
1. she allows the F1 to self-fertilize
2. she crosses a plant from the F1 to a smooth orange strain.
Choose all statements that are TRUE:
Group of answer choices
orange is dominant
spiky is dominant
all the progeny resulting from cross 1 (the selfing) will be smooth
all the plants resulting from cross 2 will be orange
green is dominant
all the progeny resulting from cross 1 (the selfing) will be spiky
smooth is dominant
there will be mixture of smooth and spiky plants in the progeny resulting from cross 1 (the selfing)
All the plants resulting from cross 2 will be green
there will be a mixture of green and orange plants in the progeny resulting from cross 2
