Question
Chapter 14.5, Problem 41AYP
Summary Introduction
To determine:
The ways by which aging affects sensory function.
Introduction:
The neurons which receive special kind of stimuli are known as sensory receptors. Sensory receptors are of four types that are specific to a particular sense. These four sensor receptors are chemoreceptors, thermoreceptors, photoreceptors, and mechanoreceptors.

So you make the same cross again (between a homozygous black seeded, mold susceptible parent and a homozygous white seeded and mold resistant parent), and, again, advance progeny by SSD to create 100 F10 generation plants. Based on the information you obtained from your first crossing experiment (Question #4), how many F10 plants would you expect to have black seeds and be resistant to mold? Assume that a toxin produced by the mold fungus has been isolated. Only mold resistant seeds will germinate in the presence of the toxin. Could you use this toxin screening procedure to have segregation distortion work in your favor in the F2 generation? Explain your answer. Info from Question 4 a. P Locus (Seed Color): Hypothesis: The null hypothesis (H₀) is that seed color is controlled by alleles at a single locus.
