Genetic diversity in agricultural crops is threatened by

In India, we find mangoes with different flavours, colours, fibre content, sugar content and even shelf-life. The large variation is on account of  

(1)  species diversity    

(2)  induced mutations    

(3)  genetic diversity    

(4)  hybridisation.
