Hi aspirent
If we consider scope then biotechnology has more scope then genetic. Genetics is the part of biotechnology.

Bio-Technology is a research oriented science, a combination of Biology and Technology. It covers a wide variety of subjects like Genetics, Biochemistry, Microbiology, Immunology, Virology, Chemistry and Engineering. It can be studied as a BSc and MSc programmes (a few universities also offer five-year integrated B.Tech /M.Tech Dual Degree Programmes after 10+2 Science) and also as a B.Tech and M.Tech courses.

Biotechnology as a subject has grown rapidly. And as far as employment is concerned, it has become one of the fast growing sector. Bio-technologists can find careers with pharmaceutical companies, chemical, agriculture and allied industries. They can be employed in the areas of planning, production and management of bio-processing industries.

On the other hand,Genetic Engineeringis concerned with deliberate manipulation of the genetic material (DNA) of a living organism by artificial methods. The study of genetic engineering involves insertion of new genetic material at an unspecified location in the host genome by isolating and copying the genetic material of interest using molecular cloning methods to generate a DNA sequence containing the required genetic elements for expression, and then inserting this construct into the host organism.
Genetic Engineering is also concerned with developing hybrid varieties of plants, making plants disease resistant. Genetic engineering techniques are used in research, biotechnology, and medicine.

Through my consideration biotechnology is better than genetic.

Best of luck
Thanks
