Question:
The term that refers to the pollinations resulting from one ramet to another ramet of the same clone.
The term that refers to the pollinations resulting from one ramet to another ramet of the same clone.
Show Hint
Since a clone is genetically uniform, mating different ramets of the same clone is genetically equivalent to self-fertilization, leading to inbreeding depression.

- Often cross pollination
- Cross pollination
- Self pollination
- Apomixis

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
To solve this question, we must understand the clonal terminology used in forest tree breeding.
A clone is a group of genetically identical plants derived from a single mother tree (ortet) through vegetative propagation methods like grafting or cuttings.
Each individual plant belonging to that clone is termed a ramet.
Step 2: Detailed Explanation:
Because all ramets of a single clone are genetically identical, they share the exact same genetic alleles.
When pollen is transferred from one ramet to another ramet of the same clone, the mating is genetically identical to pollen transfer within the same individual tree.
Therefore, this type of pollination does not introduce genetic variation and is classified biologically as Self-pollination (specifically clonal selfing).
Let us analyze the incorrect options:
- Cross-pollination: Requires the transfer of pollen between genetically distinct individuals, which is not the case for clones.
- Apomixis: This refers to asexual reproduction through seeds without fertilization taking place, which is not a type of pollination.
Therefore, pollination between ramets of the same clone is classified as self-pollination.
Step 3: Final Answer:
The term that refers to pollination between ramets of the same clone is Self-pollination.
