Answer:
a) the son will not be affected by rickets (0% chance)
b) the daughter will have rickets (100% chance)
Explanation:
Since only the father has rickets and it is a X-linked dominant trait, the mother has two normal X chromosomes. The X chromosome received from the mother by the son will not result in the rickets since the father will have contributed the Y chromosome and that does not have the gene for rickets. In case of the daughter, she will receive the defective X chromosome from her father, which will cause her to have the rickets disease.
Hope that answers the question, have a great day!

Fungi kingdom characteristicsThe kingdom Fungi includes a vast variety of organisms such as mushrooms, yeast and mold, made up of feathery filaments called hyphae (collectively called mycelium). Fungi are multicellular and eukaryotic.
It is technically the stem but it does not have any chlorophyll, it's usually called a stump or a tree stump.
During S phase, every chromosome replicates to yield two identical sister chromosomes (called chromatids ) that remain attached at their kinetochores.
