Complete question:
Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited.
A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time.
Assuming that both parents are heterozygous for the gene that causes the disease, what is the probability that the second child will also have the disease? Express your answer as a fraction using the slash symbol and no spaces (for example, 1/2).
Answer:
The probability that the second child will also have the disease is 1/16.
Explanation:
<u>Available data:</u>
- Two genes independently inherited: one for blood type, the other for disease
- Man with type A blood x Woman with type B blood
- Both parents are heterozygous for the gene that causes the disease; Dd
If the man has A blood, and the woman has B blood, and they already have an affected child, this means that they must be heterozygous for blood type too.

Answer: The Panama illness is a contagious illness that TR4, or Tropical Race 4, is a Fusarium wilt strain that kills banana plants. According to the ICA, the fungus “forms resistant structures that allow it to persist for more than 30 years,” making it tough to confine.

I think the use of ibuprofen should be questioned with the concurrent use of hydrocortisone, a 28 corticosteroid. The use of medication together increases the risk of gastrointestinal bleeding. Ibuprofen and sertraline azithromycin, or ipratropium will not cause adverse effects.
