Homologous organs are different from analogous organs. Mention the two basic characteristics that decide about analogy and homology between the two organs.

(N/A) The two basic characteristics that decide about analogy and homology are:
$(i)$ Basic anatomical structure and embryonic origin.
$(ii)$ Function performed by the organ.
In homologous organs,the basic structure and embryonic origin are similar,but the functions are different (e.g.,forelimbs of humans and wings of birds).
In analogous organs,the basic structure and embryonic origin are different,but the functions are similar (e.g.,wings of butterflies and wings of birds).
