Final answer:
A plant produced via apomixis is not a hybrid because apomixis is a form of asexual reproduction that results in a plant genetically identical to the parent, without the genetic mixing characteristic of hybrids.
Step-by-step explanation:
If a plant produces a seed by apomixis, the resulting plant grown from this seed is not a hybrid. Apomixis is a form of asexual reproduction where seeds are formed without the fusion of gametes, which means there is no genetic contribution from another plant. This contrasts with traditional hybridization, where two genetically distinct individuals contribute to the offspring's genome.
Hybrid plants are typically the result of the crossing of two different species or genetically distinct individuals, resulting in offspring with combined traits. Since apomixis bypasses the sexual reproductive process and does not involve fertilization, the plant that grows from such a seed is genetically identical to the parent plant and thus cannot be considered a hybrid.
