Answer: The probable genotype of the patient is a homozygous recessive allele (SS)
Explanation: Sickle cell is a recessive disorder, therefore it must occur in a homozygous state in order to manifest phenotypically. When it occurs in a heterozygous state AS, the dominant allele A will overshadow its effect. Sickle cell is a genetic disease caused by abnormal haemoglobin in the blood which gives the red blood cells a sickle shape denoted as S. A normal haemoglobin gives the red blood cells a disc shape and its denoted by A.
Answer:
Varicella-zoster virus
Explanation:
Varicella-zoster virus (VZV) is a virus with double-stranded DNA as its genome. It is a member of the family Herpesviridae. The virus causes chickenpox in children. It is mostly present in the latent form after the disease subsides and the same virus can cause shingles in adults under specific conditions. Therefore, shingles is also called a reactivated form of chickenpox caused by the latent varicella-zoster virus. The virus has an incubation period of 10 to 23 days and causes the formation of pus-filled small vesicles on the face or upper trunk.
