Video narration
Ek bagiche mein, baingani phoolon wale matar ke paudhon ko safed phoolon wale paudhon se paragit kiya gaya. Jaise parivaar mein, paudhon ke gun bhi peedhiyon mein dikhai dete hain. Gregor Mendel ne dekha: pehli peedhi ke sabhi paudhon par baingani phool the. Safed kahin nahi dikha. Phir unhone pehli peedhi ke paudhon ko prajanan karne diya. Agli peedhi mein safed phool laut aaye, lagbhag har chaar mein ek paudhe par. 3:1, teen baingani, ek safed. Safed gun mita nahi tha; pehli peedhi mein chhipa tha. Mendel ne virasat ke adrushya kaarkon ka anumaan lagaya; ve dikhe bina bhi aage ja sakte the. Baingani ko dominant, yaani dikhne wala, aur safed ko recessive, yaani chhip sakne wala, gun kaha. In shabdon ka matlab behtar ya taakatvar hona nahi hai. Mendel ne aaj ke arth mein genes nahi khoje. Yaad rakhiye: safed phoolon ki vaapasi batati hai, na dikhna, mit jaana nahi.
