Question 17 • TPS EdX Biology

Which best describes horse breeding?

Answer
A
Different horse and pony breeds are an example of overcompetition.
B
Selective pressure in nature has resulted in different horse and pony breeds.
C
People have manipulated the genome of horses and ponies in the lab to produce the breeds we know today.
D
People have selected the most desirable natural traits to produce different horse and pony breeds.

Explanation

Horse breeding is an example of artificial selection: people choose horses with desirable natural traits and breed them so those traits are more common in later generations. Over time, this has produced different horse and pony breeds. This is not the same as manipulating their genomes in a lab, as choice C suggests.
