Chapter 22, Problem 18TYR
Summary Introduction
Introduction:
Breathing is the process of exchange of air to and from the lungs. It has two phases, inspiration and expiration. Inspiration is breathing in of air, which reaches the lungs and expiration is removal of air by breathing out from the lungs. There are respiratory centers located in the brain stem where breathing is regulated. The medulla oblongata and pons are the central respiratory centers of the brain. The main function of the medulla oblongata is to regulate breathing. The respiratory centers have chemoreceptors which can easily identify any alteration in the pH levels of the blood, thus directing the signals to the respiratory centers to regulate the ventilation rate.

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.
