Accepted Answer

Ontogeny can be characterised as origination and development of an organism that occurs from time of fertilization of egg to adult. Phylogeny can be described as a tree or a branching diagram that shows the evolutionary relationship among various biological species based on similarities and differences between them.Ontogeny repeats phylogeny was expressed by Ernst Haeckel which explains that the development of embryo of an organism from fertilization to gestation goes through various stages of growth and development that resembles successive adult stages in the evolution of the organism's remote ancestors.
