A class has compiled this list of examples of artificial selection.
• The development by dog breeders of a variety of
poodles that have different coats that do not require
brushing
The crossbreeding of cows that have provided meat and
milk for humans for many centuries
• The breeding of domestic turkeys that have large
amounts of breast meat and a reduced wing size that
makes them unable to fly
• The creation of varieties of apples that remain crisp
throughout the winter but have less flavor
• The development of roses that will wilt quickly and have
long stems, no thorns, and no strong scent
Which three statements describe the common characteristics of all of the
examples of artificial selection?

Artificial selection always requires a detailed knowledge of the genetic makeup of a species and a familiarity with the mathematics
of inherited traits.
Artificial selection infers that a species experiences natural genetic mutation rather than reproduction planned by humans.
Artificial selection involves enhancing the natural characteristics of a species through planning and coordination of its breeding.
Artificial selection has been practiced in many forms for centuries to improve crops and livestock
Artificial selection may have unintended consequences that can reduce the benefits of a species to humans or limit its function
