Biology
1 answer:

Answer:

D. XHxh and XHY

Explanation:

since this is the only answer with genes that share a common allele, the answer is D.

In order for a recessive gene to be present, the daughter must have gained the alleles of XHXH, which in this case, is a 25% chance. The other two possibilites are XHxh, XHY, and Yxh. To further prove this, a female must have 2 X alleles and to have hemophilia, they must carry 2 H's. If they were to only have one H, they would be a carrier instead of a product.

Ratling [72]

Answer:

The correct option is : It undergoes a lysogenic cycle.

Explanation:

A virus can replicate inside a host cell by two process :

  • Lytic cycle
  • Lysogenic cycle

In the lytic cycle, the viral DNA makes copies of itself and manufactures the viral machinery inside the host cell. Eventually, the host cell bursts causing the release of the viruses. In such a condition the varicella virus would cause chicken pox.

In the lysogenic cycle, the DNA of a virus get incorporated into the DNA of the host. The viral DNA might replicate when conditions become favourable and cause diseases. In such a condition, the varicella virus would cause shingles.
