Here are some questions based on pages 75-78 of Chapter 5 of Class 12 NCERT Bio Book. Prior to the topic 5.3 "Inheritance of two genes".
A thorough reading of the above pages is an absolute must before starting to answer these questions. Take time to read, then start solving. do NOT refer book if you are not able to answer 1 or two questions. if you are not able to answer 3 in continuity, close the copy and read the pages once again.
These pretests are based on a wonderful technique of learning based on Neuroscientific Research:
The technique of Retrieval Practice. but for it to work, you must give up the greed of getting all answers right in one go. The technique aims to

These pretests are based on a wonderful technique of learning based on Neuroscientific Research:
The technique of Retrieval Practice. but for it to work, you must give up the greed of getting all answers right in one go. The technique aims to
- increase efficiency of your reading;
- help you exert your brain to improve your working memory;
- and finally build long lasting neural connections that you can rely on during your session ending examinations.
