Hi,
After doing zoology you can choose any specialisation course in genetics, biotechnology, endocrinology, immunology, applied zoology, wildlife science, ecology and you will be eligible for all these specialised courses in most of the universities. If you don't want to go for higher education, you can get jobs in government sector by clearing the exams and can sit for IAS more preferably Indian Forest Service or all State Government Forest Services. You can also crack CSIR NET (life science) or UGC NET (environment Science) or GATE (Evolution or ecology).
Thanks.
