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.

Imagine a species with three loci thought to be on the same chromosome. The recombination rate between locus A and locus B is 35

Vesnalui [34]

Answer:

<h2>Recombination rate or recombination frequency between locus A and locus C is either 2% or 50%. </h2>

Explanation:

As given,

Recombination frequency between locus A and B is 35%, means that the distance between A and B is 35 cM.

Recombination frequency between locus B and C is 33% , means the distance between B and C is 33 cM.

Therefore, if the locus C is present between A and B, then the recombination frequency between A and C would be 2%

A-----C ----------B

A---C= 2%

A----B= 35%

B---C= 33%

So, here the recombination frequency between A and C is 2%, means their distance is 2 cM.

If the locus C is as, A---35---B--33----C ; A-----B------C

A-----B= 35%

B------C= 33%

A-----C= 33+35= 68%

As rule, maximum frequency can not exceed 50%, as here the Recombination frequency between A and C = 50%.
