Question

Broccoli, cauliflower, kale, and cabbage all originated from the wild mustard plant, but farmers artificially selected these distinct crops over time. Artificial selection . Because it produces organisms with traits that people desire, a possible negative consequence for the organism is .

Answer 1

Artificial selection can create organisms that are desirable to humans but dangerous to the population (other species). It can also create new mutations, perpetuate harmful mutations, or breed the new generation having a shorter life span.

Answer 2

Artificial selection triggers the evolution of species but a negative consequence for the organism is decreased genetic variation.

Explanation:

Artificial selection is also known as selective breeding in which organism which is having desirable traits are selected from the wild type and allowed to cross to produce offspring having desired traits. Then these offsprings are interbred to produce more offsprings until all the offsprings contain the desired trait.

So artificial selection triggers the evolution of species by selecting a particular trait in the population but one of the side effect is that the genetic variation decreases in artificial selection because of inbreeding which deletes many traits that is present in wild type.

Therefore, Artificial selection triggers the evolution of species but a negative consequence for the organism is decreased genetic variation.
