Verified by Experts

The correct Answer is:
A
The principlem of segregation is the most fundamental principle of heredity that has universal application with no exception. Some workers like Bateson call the principal of segregation as the principle of purity of gametes because segregation of the two Mendelian factors of a trait result result in ametes receiving only one factor out of a pair. As a result gametes are always pure for a character. It is also known as law of non-mixing of alleles and can be demostrated through a monohybrid cross.
