CBSE Class 12: Biology notes. Class 12 Biology connects reproduction, inheritance, molecular processes and other major themes. Study each mechanism as an ordered explanation rather than a collection of terms.

What to revise

  • Reproduction: distinguish structures, stages and their roles.
  • Inheritance: connect the problem's assumptions with the predicted pattern.
  • Molecular biology: link genetic information with the processes using it.

A quick self-check

Explain one inheritance example and redraw one molecular-process diagram from memory. Check the sequence and the meaning of every symbol against your notes.
