Example of X-linked dominant trait is:
Correct answer: D. Hypophosphatemia
- A. Hemophilia A
- B. Testicular feminization syndrome
- C. Hemophilia B
- D. Hypophosphatemia

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
