They can both burn gasses.
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>.

The process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight.
<h3>WHAT IS PHOTOSYNTHESIS?</h3>
Photosynthesis is the process whereby green plants obtain their food (glucose) in the presence of sunlight as an energy source.
Photosynthesis takes place in two stages namely;
- Light dependent reactions
- Light independent reactions
Photosynthesis combines carbon dioxide and water as reactants as follows:
6CO2 + 6H2O = C6H12O6 + 6O2
Therefore, the process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight.
