Final answer:
Females with the RR genotype are affected, while males with the RY genotype are affected. Females with the RR or Rr genotypes are unaffected, and males with the RY genotype are also unaffected.
Step-by-step explanation:
In the context of X-linked recessive diseases, the question is asking about the phenotypic effect of different genotypes in males and females.
In this scenario, females with the RR genotype are affected, while males with the RY genotype are affected. Females with the RR or Rr genotypes are unaffected, and males with the RY genotype are also unaffected.
It's important to note that in X-linked recessive diseases, males cannot be carriers of the disease, whereas females can be carriers but not necessarily affected.
