Question

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.

Answer 1

Hey guys just ya know it's A anyways have a good day

Step-by-step explanation:

Answer 2

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

Step-by-step 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.
