Rh factor may be responsible for:

Correct answer: D. Erythroblastosis fetalis

  • A. Turner's syndrome
  • B. Sickle-cell anemia
  • C. AIDS
  • D. Erythroblastosis fetalis

Explanation

Yes, the Rh factor can be responsible for a condition called erythroblastosis fetalis. Erythroblastosis fetalis, also known as hemolytic disease of the newborn (HDN), occurs when there is an incompatibility between the blood types of the mother and the fetus, specifically related to the Rh factor. The Rh factor refers to a specific antigen found on the surface of red blood cells. If a mother is Rh-negative (lacks the Rh factor) and the fetus is Rh-positive (has the Rh factor), the mother's immune system may produce antibodies against the Rh factor if exposed to it during pregnancy or childbirth. In subsequent pregnancies with Rh-positive fetuses, these maternal antibodies can cross the placenta and attack the fetal red blood cells, leading to the destruction of red blood cells and causing erythroblastosis fetalis. This condition can result in severe anemia, jaundice, organ damage, and, in severe cases, fetal or newborn death. Rh factor incompatibility can be prevented and managed through Rh immunoglobulin (RhIg) administration to Rh-negative mothers during pregnancy and childbirth, which prevents the formation of Rh antibodies and reduces the risk of erythroblastosis fetalis.

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.
