Final answer:
The section 'Inherited Disorder' describes genetically-inherited human diseases, chromosomal abnormalities during meiosis, and the dramatic effects of these disorders. It also touches on ethical and social issues related to genetic disorders.
Step-by-step explanation:
In the section titled “Inherited Disorder,” the author describes genetically-inherited human diseases. This includes diseases such as sickle cell anemia, alkaptonuria, hemophilia, color blindness, and Huntington's disease. Specifically, the text details how inherited disorders can originate from abnormal behaviors of chromosomes during meiosis, with a focus on two categories: abnormalities in chromosome number and chromosome structural rearrangements. These chromosomal disorders often have significant, sometimes fatal, consequences due to the fact that small chromosome segments may contain many genes. Additionally, the section may cover the ethical, social, and medical issues surrounding genetic disorders, such as the right to privacy and concerns about genetic testing.
