Etymology-2

In Mahabharat, when army of Shri Rama reaches Sri Lanka, Ram laments over his separation from the motherland India and says to Lakshman:

अपि स्वर्णमयी लंका न में लक्ष्मण रोचते
जननी जन्माभूमिश्च स्वर्गादपि गरीयसी

Translates to: Oh Lakshman, I am amazed by the spectacular golden beauty of Lanka, but its a trifle compared to my motherland (जननी जन्माभूमि), India which still holds the dignity, in my Heart, above even the Holiest of holy Heaven.

The word under focus here is 'जननी' which means mother. This word manifests itself in different languages, including English in different forms.
The basic form, a 'मूळ धातू’ of sort for this word is 'जनन', which is a generic word for anything related to birth. In marathi, 'जन्म’ means birth. 'प्रजनन’ in Sanskrit is the 'Act of reproduction'.
Intrestingly, English also uses this word in differnt form but with similar meaning. 'Genesis' is the 'Book of the begining' in Bible. 'Genesis' comes from the Latin 'Genus', meaning 'Birth'. Genetics is the science of the Genesis.
Medical science has adopted the word 'Gene' to represent a sequence of DNA, to represent the functional unit of inheretance.
