Both touch different aspects of the subject. BE is more about the engineering side while you learn a lot more in B.Sc.

Hi Harika,
You can definitely pursue genetic engineering after B.Sc in CBZ if you're referring to B.Tech in genetic engineering as it would require class 12th from PCM for the eligibility criteria which I am assuming you to have it. For Masters in the same, you'll have to consult the institutes you're wishing to study it from.
Feel free to raise more queries.
All the best.
