Glucоcоrticоids аre steroid hormones thаt control cellulаr responses through several different signaling pathways. One of the signaling pathways involves the glucocorticoid receptor, an intracellular protein that is activated by binding to a glucocorticoid molecule. A simplified model of the glucocorticoid receptor signaling pathway is represented in Figure 1. The figure presents a simplified model of the glucocorticoid receptor signaling pathway. A plasma membrane separates the extracellular space outside the plasma membrane from the cytosol inside the plasma membrane. A glucocorticoid is represented in the extracellular space. An arrow indicates that the glucocorticoid crosses the plasma membrane to the cytosol. In the cytosol the following three stages are represented in order from left to right. First, accessory proteins are associated with an inactive glucocorticoid receptor, then the glucocorticoid approaches the inactive glucocorticoid receptor and the accessory proteins dissociate from the inactive receptor, then the glucocorticoid is bound to the activated glucocorticoid receptor, and this complex moves into the nucleus, where a label indicates that changes in gene expression take place. Figure 1. A simplified model of the glucocorticoid receptor signaling pathway Which of the following statements best predicts the effect of a mutation that results in a loss of the glucocorticoid receptor’s ligand binding function?
A mаle fruit fly (Drоsоphilа melаnоgaster) with red eyes and long wings was mated with a female with purple eyes and vestigial wings. All of the offspring in the F1 generation had red eyes and long wings. These F1 flies were test crossed with purple-eyed, vestigial-winged flies. Their offspring, the F2 generation, appeared as indicated below. 283 Members of the F2 Generation Phenotype Number of individuals Red eyes, long wings 125 Purple eyes, vestigial wings 124 Purple eyes, long wings 18 Red eyes, vestigial wings 16 If in the F1 and F2 generations the same characteristics appeared in both males and females, it would be safe to assume that these traits for eye color and wing length
