Elements, such as helium, depicted here, are made up of atoms. Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
The model of the atom can be broken down into three constituents parts – protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge.

Explanation:
Beta-thalassemia major is a hereditary disorder that usually causes severe anaemia. This mutation/disorder eventually leads to death if untreated especially during in the first two years of infancy. The treatment usually involves the transfusion of blood to clear the phenotypic blockage caused by the mutation. However, it requires both alleles to have the thalessemia mutation for a patient to be said to have beta-thalassemia major. Hence, <u>it is </u><u>not true</u><u> that it involves just the x allele and thus affects males more often than females</u>.
