The farmer can improve the milk yield by breeding those cows with desirable characteristics.
Explanation:
- The farmer should inseminate those cows which produce more milk. This process will be described as artificially selecting those cows which had better desirable characteristics.
- The cow which produced more milk will pass on its characteristics to its offspring. When these offspring are mated, there will be increase in the milk content of the cows.
- In this way, artificial selection can be used to improve the milk content of the cows.
