The original source of all genetic variation is _____.
zmey [24]

Answer:

C. Mutation.

Explanation:

The mutation is the source of all genetic variation. There are two types of mutations. One is the natural mutation, and another is the artificial mutation. The natural mutation occurs due to the environmental cause, and humans using various mutagens do artificial mutations.

These two types of mutations always bring variation in any organism. This variation can be positive or can be negative too. Natural mutation is not possible to control so that anything can happen. Either positive or negative changes can occur. But in the case of artificial mutation, in 90% cases, positive results come in genetic variation.

Do the virus Chickenpox. I will find a image no need to worry about that.
Black_prince [1.1K]

The chickenpox virus is a highly contagious disease that can cause itchiness and produces a blister-like rash. It is caused by the varicella-zoster virus (VZV).

1. Varicella-zoster virus has the ability to switch from a latent lysogenic cycle to an active lytic cycle that reactivates after dormancy.

2. Varicella-zoster virus infects human cells. Basically, it infects and replicates the cutaneous fibroblast and epidermal cells and the several types of immune cells.

3. The person typically contracts this virus through inhalation. It enters the host's respiratory tract where it replicates in the nasopharynx as well as the regional lymph nodes.

4. This virus is characterized by red itchy blisters that can spread over the entire body.
