#biological terminology

• The alleles — The definite articulate plural form of the feminine noun alelă; it specifically and directly defines the alternative variants of the same gene occupying a homologous chromosomal locus, viewed as clearly defined objects of study within a diploid organism or a biological population.
• Anceps — A term of Latin origin used across disciplines to describe an entity with a double, ambiguous, uncertain, or vacillating character. In ancient metrics, it defines a syllable whose structural length can be either short or long depending on verse requirements. In botany, it describes flattened stems or plant organs featuring two sharp, opposite edges, while in medicine it indicates an uncertain or fluctuating prognosis.
• Anisoploid — Having an asymmetric, unequal, or non-uniform number of chromosome sets; an organism, cell, or hybrid characterized by anisoploidy. In plant genetics, it describes individuals resulting from crosses of parents with different ploidy levels (for instance, a tetraploid with a diploid), resulting in an aberrant or unbalanced number of chromosomes in the somatic set.
