During puberty, significant changes occur in the human body due to the activation of the reproductive system. This process is controlled by hormones, which act on the sexual organs and also on other body systems. Explain how the pituitary gland and the hypothalamus, both located in the brain, interact to control puberty. In addition, discuss the role of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and human chorionic gonadotropin (hCG) in the development and maintenance of reproductive structures, and how these hormones can be targets for regulation in infertility treatments. Finally, mention and briefly explain a medical condition that may arise due to alterations in the functioning of the reproductive system during puberty.

In a pea crossing experiment, Gregor Mendel observed the independent segregation of two different characteristics of the organism. Based on Mendel's Second Law, known as the Law of Independent Assortment, which of the alternatives below correctly represents the phenotypic ratios observed in a dihybrid cross when the characteristics are controlled by two pairs of alleles?
