Question

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

For the first blank, the choices are:
-Doesn’t affect evolution
-Stops evolution of the species
-triggers evolution of the species

For the second blank, the choices are:
-decreased genetic variation
-an inability to carry out the basic functions of life
-an inability to mutate DNA

Answer 1

Artificial selection triggers evolution of the species.

Because it produces organisms with traits that people desire, a possible negative consequence of the organism is decreased genetic variation.

Answer 2

1.-triggers evolution of the species

2.-decreased genetic variation

Step-by-step explanation:

Artificial selection is when human observe a characteristic on certain plants or animals that are likeable or that better suits our necessities and starts to breed or reproduce specimens with those specific characteristics, one example of that are the pug dogs, they were artificially selected over the time and eventually came to look how they do today, this decreases genetic variation since the products of the artificial selection that do not match the desired characteristics are left to day or its reproduction is stopped.
