First of all, hemophilia is an x-linked recessive and recessive disease. So it's a genetic disease.

Therefore, there is no possibility of snatching it from his son. It can come from mom or dad. If the mother and father do not have this disease, as in the question, the mother carries this disease recessively. If it was a girl, she would be less likely to get the disease, as she would have to inherit the genotype of this disease from both the mother and the father. however, since her children are boys, she received the disease gene from the mother's recessive gene region. Therefore, the boy has hemophilia in the XhY genotype.

It defines the pattern in which sediment layers are layered over each other and may occur on a scale of hundreds of meters, even down to sub-millimeter.

It also results from variations in texture or composition during deposition. Delays in deposition may also permit for variations to the older deposits before coverage given by new sediments. This mechanism in sedimentary rocks change in both, the degree of prominence and in structure details.
