A carrier female for hemophilia can pass the defective allele to:
Correct answer: C. Both sons and daughters
- A. Only sons
- B. Only daughters
- C. Both sons and daughters
- D. Neither sons nor daughters
Explanation
Carrier female (XHXh) can pass Xh to sons (XhY = hemophiliac) or daughters (XHXH = carrier). Thus, both can inherit the allele.

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.
