Hi,
As per your query, you can consider these options for graduation degree in relations to UPSC:
1. Physics/ chemistry honors.
2. Zoology honors.
3. Psychology.
4. Law.
All the best.

You need SLET/NET score and better to go with Ph.D. along with the job. Scores provide you the JRF till the age of 28 and lectureship with no age limit.

Every year, a lot of science graduates and post-graduates crack Civil Service Examination. Any graduate with good academic records, self-confidence, with proper planning and preparation can crack Civil Service examination. All the Best!

Genetic engineering is a very broad discipline that is best broken down into its areas of practical application in order to be most easily understood. At the highest level, genetic engineering can be sub-divided into the creation of genetically modified (GM) plants, animals and micro-organisms, as well as the application of genetic engineering in healthcare, otherwise known as genetic medicine. In turn, genetic medicine may be usefully sub-divided into the fields of genetic testing, pharmacogenetics, and gene therapy.

You should opt for Masters in biology.

Dear,
For UPSC, you need to be graduate first. Complete your graduation first in the discipline of your interest. I detest start preparing for logical questions, basic maths and General knowledge.
