| 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. |
| (v) Assertion [A] At \[{{F}_{2}}-generation\] in monohybrid cross, both parental traits are expressed in the proportion of 3:1. |
| Reason [R] The contrasting parental traits show blending at \[{{F}_{2}}-generation\]. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true, but R is not the correct explanation of A
C) A is true, but R is false
D) A is false, but R is true
Correct Answer: C
Solution :
[c] A is true, but R is false. R can be corrected as In \[{{F}_{2}}-generation\], both the parental traits of a character are expressed in the ratio of three dominant to one recessive. There is no blending of characters in \[{{F}_{2}}-generation\] because blending inheritance ratio comes out to be 1 : 2 : 1
