B. All children born in future generations will be affected by this disorder.

Amani Kidd · Answer 2

According to the information given in this excerpt, what we can conclude about this gene mutation is that all children born in future generations will be affected by this disorder. The correct answer is B.

Explanation:

We can infer this conclusion about this disorder because, in the example given, we can see how with just one of the parents being affected by the gene mutation, all three of the children are affected. Not one, not two, all three of them. This means that every future generation will be affected by the same gene, no exception because three from three were affected, this is the 100%.
