Question

Which is the best example of natural selection?A farmer breeds only the cows that produce the most milk.O A peacock possesses bright feathers to attract a mate.A scientist manipulates the genes of a fox so that it will produce white offspring.O A rose grower cross-pollinates to produce brightly-colored flowers.

Answer 1

A peacock possesses bright feathers to attract a mate.

Step-by-step explanation:

Artificial selection is when humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection. A farmer breeding cows that produce most milk, a scientist manipulating the genes of a fox so that it will produce white offspring, and a rose grower cross-pollinating to produce brightly-colored flowers are all examples of artificial selection.

Among all option, a peacock possessing bright feathers to attract a mate is the best example of natural selection as the processes of natural selection favour an increase of alleles that produces an individual with a combination of characteristics that has better chances of survival and reproduction.

Answer 2

Natural selection is the process through which populations of living organisms adapt and change. Variations means that some individuals possess traits that are better suited to the environment than others.

Option 1 is artificial selection

Option 2 is sexual selection

Option 3 is artificial selection

Option 4 is natural selection

Plants have evolved many different shapes, sizes and colors of flowers in order to attract animal pollinators. Animal-pollinated flowers are brightly colored and fragrant while wind-pollinated flowers are smaller, dull in color and unscented.

Answer - Option 4
