Father and son are color blind, mother is healthy. Is it correct to say that the son inherited the disease from his father?

Wrong. A son has two chromosomes, one he receives from his mother – this is X, the second from his father – this is Y, she determines the gender of the boy. The gene responsible for the disease is localized only on the X chromosomes, and in this case it could not have passed from a sick father. This means that it was inherited from a mother who has two X chromosomes, and one of them contains the disease gene (n), suppressed by the dominant gene for normal color perception (H), located on the other chromosome.
R XNXn X XnY
F1 HNHn (healthy girl), HnHn (sick girl), XNY (healthy boy), HnY (sick son).
