    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.
