Question 44
Mendelian InheritancePawpaw seeds collected from a tree with many desirable agronomic qualities did not give rise to plants of desirable characters as the parent because
- A.seeds are not reliable for propagating plants
- B.uncontrolled out-crossing can introduce unwanted variability
- C.vegetative propagation is the best form of reproduction for all crops
- D.seeds were not physiologically mature at harvest.
Show the answer and explanation
Answer: B (uncontrolled out-crossing can introduce unwanted variability)
Explanation
The seeds came from cross-pollination with unknown plants, so they carry new gene combinations and the offspring vary from the parent tree.
