Which of the following is true about the occurrence of erythroblastosis foetalis?
Correct answer: D. Occurs when mother is Rh-ive and father is Rh +ive
- A. Occurs when both father and mother are Rh +ive
- B. Occurs when both father and mother are Rh -ive
- C. Occurs when mother is Rh+ive and father is Rh -ive
- D. Occurs when mother is Rh-ive and father is Rh +ive
Explanation
Erythroblastosis fetalis (EF) is a condition that occurs when there is an incompatibility between the blood types of a mother and her fetus. Specifically, it occurs when:- The mother is Rh-negative (Rh-)- The father is Rh-positive (Rh+)- The fetus inherits the Rh+ antigen from the fatherDuring pregnancy, the mother's immune system may recognize the Rh+ antigen on the fetus's red blood cells as foreign and produce antibodies against it. These antibodies can then cross the placenta and attack the fetus's red blood cells, leading to hemolysis (breakdown of red blood cells) and potentially severe anemia in the fetus.

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.
