Which of the following is an example of pleiotropy?
Correct answer: C. Sickle cell anaemia
- A. Haemophilia
- B. Thalassemia
- C. Sickle cell anaemia
- D. Colour blindness
Explanation
Pleiotropy refers to the phenomenon where a single gene has multiple effects on an organism's phenotype. Among the options provided, "c. Sickle cell anemia" is an example of pleiotropy because the mutation in the hemoglobin gene affects various physiological processes, leading to a range of symptoms and complications beyond just the structure of hemoglobin

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.
