Genetic disorders are caused by mutations in genes. These genes consist of DNA and are inherited by the organism by its parents. Genes code for specific amino acids, and they are so complex that we still do not completely comprehend the function of every gene in the human body so we cannot remove them in order to fix a disease. Moreover, every cell in an organism's body has the same genome (except the gametes) so it is not possible to delete the faulty gene from the cells.
Answer;
The amnion
Explanation;
-The amnion is a tough, thin membrane that surrounds a developing fetus in mammals, reptiles, and birds. It is the first of the three cavities (amnion, chorion and yolk sac) in the embryo and is formed on 8 dpc.
-In the human body, the amnion is the first of three cavities, including the chorion and yolk sac, that work together to keep the developing fetus nourished and protected.
-The amnion provides a protective environment in which the fetus' temperature is regulated and protects the fetus from friction caused by the mother's movements.
