Dairy cows are selectively bred for larger udders to produce more milk. A disadvantage of this selective breeding is that these cows have difficulties producing more offspring. Which best describes when selective breeding would no longer be advantageous for the dairy cow farmers?

A

Selective breeding would no longer have an advantage when dairy cows have large udders and multiple offspring.

B

Selective breeding would no longer have an advantage when dairy cows could not produce offspring.

C

Selective breeding would no longer have an advantage when dairy cows produced more offspring than before.

D

Selective breeding would no longer have an advantage when dairy cows produced both milk and offspring.

Selective breeding would lose advantage, when dairy cows have large udders and multiple offspring.

Explanation:

Selective breeding though have lead to increase in productivity, but it has many disadvantages too. They are:

Loss of diversity of species There is a chance of genetic mutations, which reversely decrease productivity. The large udder of cow though store higher amount of milk but it is matter of very discomfort for the cow. Offspring with different traits may be generated. Hampers the natural evolutionary process and often lead to suppression of a gene.
