Solution


Q.

Read the passage given below and answer the following questions from (i) to (v):

Gregor Mendel, in 1865, paved the way for the analysis of the underlying genetic basis of traits by setting out to understand the principles of heredity. As per Darwin’s observations, in nearly all populations individuals tend to produce far more offspring than are needed to replace the parents. He also observed that it is very rare for any two individuals to be exactly alike. All the natural variations among individuals lead to natural selection. Individuals born with variations that present an advantage in obtaining resources or mates have greater chances of living and reproducing offspring who would inherit and carry forward the favourable variations. At the same time, individuals with different variations might be less likely to reproduce.
