Answer:
Since sickle cell disease is a disorder with an autosomal dominant inheritance pattern, and in light of the lack of data, it could be said that the only way for Pat and Tracy to have a child with sickle cell disease is for both of them to be healthy carriers of the gene, with a 25% probability.
Explanation:
Considering that both Pat and Tracy each have a sibling with a sickle cell trait and that both they and their parents are healthy, it must be assumed that some of their parents are healthy carriers:
- Pat and Tracy do not have sickle cell trait. In this case, there is no chance that they will have a child with sickle cell disease.
- Either Pat or Tracy has the trait, but the other does not. It is possible that at least one of their children is a healthy carrier.
- If both Tracy and Pat have sickle cell trait, the chances of having a child with sickle cell disease are:
Alelles R r
R RR Rr
r Rr rr
RR: healthy (25%).
Rr: healthy carrier (50%).
rr: sickle cell disease (25%).
<em>If Pat and Tracy are healthy carriers of the gene that determines sickle cell disease, the chance of having a child with the disease is 25%</em>.

Different steps of the oxidative decarboxylation of pyruvate by the pyruvate dehydrogenase pdh complex are given by placing them in the order as followed.
<h3>What is Oxidative decarboxylation?</h3>
The Oxidative decarboxylation reactions are oxidation reactions wherein a carboxylate institution is removed, forming carbon dioxide. They regularly arise in organic systems: there are numerous examples withinside the citric acid cycle. This sort of response probable began out early on the starting place of life.
- Pyruvate reacts with TPP and is decarboxylated, forming hydroxyethyl-TPP.
- The lipoamide arm movements to the energetic E underline three in which the decreased lipoamide is oxidized through FAD, forming the energetic lipoamide and triangle down ADH2 .
- ADH_ is reoxidized to FAD, lowering NAD to NADH.every so often known as thiamine.
- The acetyl lipoamide arm of E_ movements to the energetic of E_ , in which the acetyl institution is transferred to CoA forming acetyl-CoA and the decreased shape of lipoamide.

Fiction is made up, usually in a narrative form, and non-fiction is based on real events.
ANSWER
A
Explanation
Aa × Aa will give rise to aa which is the recessive trait. this can also be called AUTOSOMAL RECESSIVE. this talks about the child showing a particular trait that is not seen in the parents trait.
