Hii

Sorry but i am not able to get which college are you asking about. Please mention the name of the college so that i can help you with the procedure of admision.
In general the eligibility for genetic engineering UG course is qualification of class 12th with physics, chemistry and biology as core subjects with atleast 55%.
Maths is not compulsory. But some colleges do ask for maths as a compulsory subject.
So if you mention the college i can help you better.

Hope this helps.

Thanks!
