1.	Give scientific reasons on:A carrier or sufferer of sickle-cell anaemia should avoid marriage with another carrier or sufferer.
Answer» Sickle-cell anaemia is a hereditary disease caused due to mutation of a single gene. It is a monogenic disorder that occurs due to changes in a gene during conception. If father and mother both are sufferers or carriers of sickle-cell anaemia, their offsprings are likely to suffer from the disease. Therefore, a carrier or sufferer of sickle-cell anaemia should avoid marriage with another carrier or sufferer.
