Which is an example of SELECTIVE BREEDING ? (also called artificial selection)
A giraffe’s long neck.
Training a horse to run faster.
Clipping a horse’s tail so it is not too long.
Cross breeding a labrador retriever with a poodle.
The purpose of selective breeding is to
Create animals and plants with desirable traits
Get smaller animals and plants
The process where organisms best fit for the environment are more likely to survive and reproduce.
natural selection
adaptation
hibernation
selective breeding
hybridization
A genetic characteristic that allows an organism to survive and reproduce.
natural selection

In a population of desert plants, the timing of their blooming varies greatly. Some bloom early in the morning, others at mid-day, and others after dark. What environmental pressure might be an advantage for those plants that bloom after dark?
there is an increase in the population of nocturnal pollinators
there is a decrease in the strength of solar radiation
there is an increase in herbivores that forage at night
there is a decrease in water for root absorption
Mountain lions are large cats and the top predator in their habitat. A population of mountain lions may vary in several characteristics. If a prey becomes scarce, competition between mountain lions for food will increase. Which variation would provide an advantage to the individuals that possessed it?
a spotted coat
short fur
long legs
abundant whiskers
A farmer wants to increase the amount of food produced by corn crops. If the farmer selectively breeds the plants, for which trait should the farmer select?
taller stems
deeper roots
resistance to pesticides
more cobs on plant
The process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variation.
Evolution
natural selection
adaptation
extinction
The breeding of organisms for desired characteristics.
natural selection
variations
selective breeding

B) A bird's ability to sing
C) A fish swimming in water
D) A dog's ability to bark
What is the primary goal of selective breeding in agriculture?
A) To increase genetic diversity
B) To produce offspring with desired traits
C) To allow natural selection to occur
D) To eliminate all genetic mutations
In an experiment, a scientist observes that a certain plant species has developed thicker leaves over generations in a dry environment. What is this an example of?
A) Selective breeding
B) Natural selection
C) Genetic engineering
D) Artificial selection
