Principles of Inheritance & Variation (Part II): Pretest

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 

• 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.

So here we go, questions on pages 75-78:

1. According to Mendel the discrete units that controlled characters are _________.
2. Expression of only one of the dissimilar characters in F1 is controlled by Law of__________.
3. Of the 2 dissimilar alleles present in an organism, only one goes in a gamete. This is due to law of ___________.
4. Homozygous organisms form ___ type(s) of gametes; while heterozygous form  ___ type(s) of gametes.
5. Identify the plant & answer the questions below:
   
6. Which are the dominant & recessive flower colours in this plant?
7. What is the significance of pink flowers?
8. Is it according to Mendel's law? answer Yes/No.
9. Which types of Biomolecules are responsible for action of genes?
10. Which type of Biomolecules are responsible for ABO type blood groups?
11. 'I' is the gene responsible for blood groups. What does I stand for? 
12. How many forms of I genes (alleles) control blood groups? what is this phenomenon known as?
13. Based on study of inheritance pattern of Blood Groups we can say that dominance is relative. Justify.
14. Blood Group AB represents Codominance which is an exception to Law of _________. Can you explain how?
15. Gene B in pea seeds controls 2 characters. Can you name the 2 characters? Can you name this special phenomenon?
