Hii!
Yes, you can pursue BSc genetics without studying maths in class 1th and 12th.
The Eligibility criteria for the course states that the candidate must have passed class 12th with minimum 50% marks in PCB Subject combination from a recognised Board of education.
There are not many Colleges in Mumbai for it. So let me list out some of the good Colleges providing this course across India-
* Padmashree Institute of management and sciences, Bangalore
* Dyal Singh College, New Delhi
* Kakatiya University, Warangal
* Dayanand sagar Institute, Bangalore
* AWH special College, Calicut
Etc.,
Hope this helps.
Good luck!
