    Direction Read the following and answer the questions from given below Mendel is known as the 'Father of Genetics' because of his ground breaking work on inheritance in pea plants 150 years ago. At the age of 21 Mendel while working in a monastery in Brunn (now in the Czech Republic) began a series of experiments in their botanical garden. He found out how traits are passed from one generation to another, i.e. inheritance. He studied this in peas [Pisum satwum) because they are easy to grow and can be shown each year.
    (iii) Mendel was lucky to work on pea plants for his experiment because

    A) pea flowers are normally self-pollinated, but can be readily cross-pollinated

    B) there are several varieties in peas with observable alternative form of a trait

    C) the selected seven characters in the experiment are located on the same chromosome

    D) the selected seven characters were located on different chromosomes

    Correct Answer: D

    Solution :

    [d] Mendel worked on garden pea. He choose only those characters which showed consistent results. He worked on seven characters. These characters showed complete independent assortment despite the seven characters chosen by him were present on four different chromosomes, i.e. 1, 4, 5 and 7
