What happens when a Rh -ve woman, married to a Rh +ve man conceivesa child who is Rh +ve?
Correct answer: A. Maternal-foetal incompatibility
- A. Maternal-foetal incompatibility
- B. Paternal-foetal incompatibility
- C. Cancer of fetus
- D. Death of mother
Explanation
When an Rh-negative woman is married to an Rh-positive man and conceives a Rh-positive child, there can be a potential for maternal-fetal incompatibility. This occurs when the Rh-positive antigens from the fetus enters the bloodstream of the Rh-negative mother during pregnancy or childbirth. The mother's immune system may recognize the Rh-positive antigens as foreign and produce antibodies against them. These antibodies can cross the placenta and attack the red blood cells of the Rh-positive fetus, leading to various complications.

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.
