IPA: /aɪˈzɒdʒəni/
KK: /aɪˈzɒdʒəni/
A state or condition where two or more things are derived from a common origin or have a similar structure.
The isogeny of the two species indicates they share a common ancestor.
Isogeny → It is formed from "iso-" (from Greek "isos", meaning equal) and "genes" (from Greek "genes", meaning born of or produced by). The word "isogeny" refers to the process of producing equal or similar offspring or forms.
Think of 'equal' ('iso-') and 'produced by' ('genes') to remember that isogeny means producing equal or similar forms.
