Pedigree
Which statement is true comparing natural selection and artificial selection?
In natural selection, traits benefit humans and in artificial selection, the traits benefit the species
In natural selection, traits benefit the species and in artificial selection, the traits benefit humans
In natural and artificial selection, the process takes hundreds of years to occur
In natural and artificial selection, nature determines what traits will be passed down to offspring.
Humans often use methods of artificial selection, such as selective breeding, to produce horses with specific traits.
Which statement best describes how selective breeding helps horse breeders produce the most desirable traits for racing?
Selective breeding produces horses with a higher rate of survival due to an increase in the genetic diversity of the horse offspring.
Selective breeding helps breeders control which traits are passed on by producing horse offspring that only have the desired traits.
Selective breeding uses two horse parents with the desired traits to increase the chances of passing the desired traits on to offspring.
Selective breeding uses two horse parents with unknown traits to produce offspring with genetic variations and different traits.
Which of the following statements is true regarding selective breeding?
Selective breeding only works in plants.
Selective breeding produces changes in genes.
Selective breeding only works in animals.
All statements are true.

Galapagos finches developed different varieties of beaks to more easily fit the various food sources on different
Rat snakes have developed a variety of colors and patterns to better camouflage in a number of different habitats.
