Final answer:
No, a chimaera cannot be propagated true-to-type by layering because chimaeras contain two or more genetically distinct types of cells, and layering does not ensure the full range of genetic material present in the parent is transferred. Hence, the correct option among the one is Option B.
Step-by-step explanation:
Would you predict that a chimaera could be propagated true-to-type by layering? The answer is No, i.e., Option B. Chimeras are organisms that contain two or more genetically distinct types of cells. These distinct cell types can arise from different zygotes in the case of an organism that has fused together, or from one organism as a result of a mutation.
Since chimerism involves distinct genetic makeups in one organism, vegetative propagation methods like layering are not reliable in reproducing chimaeras true-to-type because each layer may not contain the full range of genetic material present in the parent.
A chimaera's unique pattern and characteristics are typically the result of the combination of cells from different genetic types. While cloning might produce a genetically identical organism, layering will not ensure that the genetic composition of all the different cell types is passed on to the new plant.
