Aneuspory
Definition
A particular type of apomixie or anomaly in spore formation within certain plant species, characterized by the unequal or aberrant distribution of chromosome numbers during meiotic division. This structural phenomenon leads to the appearance of spores with an irregular genetic complement, directly affecting reproductive viability and generating specific phenotypic variations within plant populations.
