Question 310 pts

Which one of the following statements about Adaptation is true?

Group of answer choices

Adaptation is possible when all the alleles in a gene pool are the same.

An individual that has learned how to survive cold winters has become adapted to the cold.

A population that has an increase in frequency of alleles for thicker fur has become adapted to the cold.

Adaptation results when cold temperatures cause mutations for longer fur.

Answer 1

1. Four Pentadactyl (five-fingered) appendages or limbs (4 legs or 2 arms and 2 legs) is the property that is not common to all the vertrbrates.The common characters of vertebrates are a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. The 4 appendages are the properties of tetrapods a division of vertebrates.

2. Comparative Anatomy is the comparative study of the similarities and differences between similar structures of related organisms.They provide the evidences toward evolution.The analogous and homologus anatomical structures in different species help in this.

3. A population that has an increase in frequency of alleles for thicker fur has become adapted to the cold.

This statement is true.

The organisms that has dveloped the favaourable alleles are better adapted to survive in the environment.

4.Artificial selection is the process by which Farmers and horticulturalists have bred broccoli, cauliflower, kale, and cabbage from the wild mustard plant.

Artificial selection is the intentional selection of the favourable traits and the elimknation of the other unfavourable traits by breeding over generations.
