The problem, due to Rh - factor arises when the blood of two (Rh + and Rh - ) mix up:
Correct answer: D. Both A and C
- A. During pregnancy
- B. In a test tube
- C. Through transfusion
- D. Both A and C
Explanation
The problem due to the Rh factor arises when the blood of individuals with different Rh statuses (Rh+ and Rh-) mixes, leading to Rh factor incompatibility. This can occur during pregnancy (option a) and through blood transfusion (option c). Both scenarios can result in sensitization and the development of anti-Rh antibodies in the recipient's immune system. Therefore, option (d) "Both (a) and (c)" is the correct answer.

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.
