Sickle cell disease is a genetic disorder that gives red blood cells a crescent shape instead of the typical disk shape. This genetic disease is recessive. If two individuals who have one recessive gene have four children, what percentage of the children will show symptoms of sickle cell disease?

    25 percent if you put this into a punnet square mainly if 2 people have one dominant and one recessive your end result will be 25 percent whole dominant 50 percent half dominance, and half recessive and 25 percent whole recessive so your answer is 25 percent

    Please don't give out direct answers :) @kingalex123 Instead, try engaging the asker so they can learn better and understand where your answer is coming from.

    It is not recessive. That is a oversimplification. Having one defective copy of the gene does cause very slight changes in red blood cells. Looking at the individual level, these small changes are not harmful, looking at populations across time, the changes are harmful. To have the actual disease that can kill a person though, two faulty copies are needed.

    Actually, I did engage...sort of because I explained my reasoning as any other textbook would do @Aureyliant

    Well, technically the answer is impossible to determine. The math says that random choice should result in 25% of the children having two faulty copies, but we cannot answer how many children actually show symptoms (have two faulty copies). Could be all 4, 3, 2, 1, or 0.
