Questions

Which syllabus does this course follow?

It follows the UP State Universities NEP 2020 common minimum syllabus for B.Sc Botany, Semester 6. Where your own university's syllabus differs, the centre follows your university's syllabus and question pattern.

Are genetics numericals asked in the exam?

Yes. Ratios, chi-square and map-distance problems are practised unit-wise in this course.

Is there a test after the course?

Yes. Unit-wise multiple-choice tests and a final exam paper are included for semester exam practice.
