Answer:
If both parents do not have sickle-cell anemia, than the possibility is low.
Explanation:
If both parents have the sickle-cell trait, their offspring has a 25 percent chance of getting sickle cell anemia and a 50 percent risk of them having sickle cell trait. Meanwhile, there is also a 25 percent chance of the child not getting it at all.
If one parent has sickle cell anemia and the other has sickle cell trait, then their offspring with have a 50 percent chance of getting sickle cell anemia and a 50 percent chance of getting a sickle cell trait.
When both parents have sickle cell anemia, their child will definitely have it.
There is no context so I will just explain what a constant is:
In an experiment following the scientific method, a constant is a variable that cannot be changed or is purposely not changed during the experiment.
An example would be:
If a researcher wanted to study the effects of temperature on the growth and development of garden snakes, the experimental variable for the experiment would be temperature. All other variables would need to remain consistent to avoid invalid data. The size of the cage, amount of light, food and many other variables would need to remain constant to ensure accurate results and a valid study. Those variables are constants. Some variables are not under a scientist's control, but are still considered to be constants. These constants are called universal constants and include gravity, the speed of light and electronic charge. Universal constants do affect experiments but will be constant through an experiment without being controlled by the scientist.
