Chapter 27, Problem 11WIO
Summary Introduction
To explain:
The roles of rods and cones in the sense of sight.
Concept introduction:
Photoreceptors are the sensory receptors which is responsible for the detection of light. Photoreceptors are of two types the rods and cones. These photoreceptors are present in the retina of the human eye. These photoreceptors transmit the neural impulses to the brain and induce a sense of sight.

The Esp gene encodes a protein that alters the structure of the insulin receptor on osteoblasts and interferes with the binding of insulin to the receptor. A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2).
Which of the following claims is most consistent with the data shown in Figure 2 ?
A Esp expression is necessary to prevent the overproduction of insulin.
B Esp protein does not regulate blood-s

In the tomato, red fruit (O+) is dominant over orange fruit (0), and yellow flowers (W+) are dominant over white flowers (w). A cross was made between true-breeding plants with red fruit and yellow flowers, and plants with orange fruit and white flowers. The F₁ plants were then crossed to plants with orange fruit and white flowers, which produced the following results: a. b. 333 red fruit, yellow flowers 64 red fruit, white flowers 58 orange fruit, yellow flowers 350 orange fruit, white flowers Conduct a chi-square analysis to demonstrate that these two genes DO NOT assort independently.
