Hereditary rickets is a sex-linked dominant trait. This means that if an individual has at least one copy of the dominant allele (H), they will have the trait.

1. XHXH: This genotype would result in someone having rickets because they have two copies of the dominant allele (H).

2. XHY: This genotype would also result in rickets. Even though males only have one X chromosome, the presence of the dominant allele (H) is enough to express the trait.

3. XHXh: This genotype would result in rickets as well. Even though there is one recessive allele (h), the presence of the dominant allele (H) on the other X chromosome is enough to express the trait.

The genotype XhY would not result in rickets because there is no dominant allele (H) present. Similarly, XhXh would not result in rickets because both X chromosomes carry the recessive allele (h).
