IPA: /nɒnˈælɪk/

Describing genes or traits that do not act as alleles, meaning they do not have alternative forms that can be inherited in the same way.
The study focused on nonallelic interactions between different genes.
Nonallelic → It is formed from "non-" (meaning not) and "allelic" (from "allele", which comes from the Greek "allelon", meaning of one another). The word "nonallelic" refers to genes that are not alleles of the same locus, meaning they do not correspond to one another.
Think of 'non-' meaning 'not' and 'allelic' relating to genes that are 'of one another'. So, nonallelic means genes that are not corresponding to each other.
