Which of the following statements about zebra stripes is most accurate based on the information provided?

The stripes are unique to each individual zebra, similar to human fingerprints, and are used for visual identification.
The stripes are a result of genetic mutations that occur randomly in zebra populations.
The stripes serve as a form of camouflage in grassland environments.
The stripes may help disrupt the ability of bloodsucking horseflies to land on zebras, reducing disease transmission. (correct)

The term 'zebra fingerprints' refers to which of the following?

The unique pattern of stripes found on each individual zebra, serving as a form of visual identification. (correct)
The unique genetic makeup of each zebra species, determined by their chromosomal composition.
The distinct vocalizations and auditory patterns used by zebras for communication within their social groups.
The distinctive hoof prints left by zebras on the ground, used for tracking purposes.

If a horse is dressed like a zebra, what is the most likely reason for this practice?

To help the horse blend in with zebra herds and facilitate social integration.
To confuse predators and make the horse less vulnerable to attack.
To attract potential mates by mimicking the appearance of zebras.
To provide protection against biting insects, as the striped pattern can confuse or deter them from landing on the horse's body. (correct)
