Summary Introduction
To describe: The gene-for-gene hypothesis.
Introduction: Plants are attacked by many factors, such as bacteria, fungi, animals, protists, and so on. Several defence mechanisms occur in plants, which block or decrease the infection. The first line of defense is thick cell walls that are covered with a resilient cuticle. The second line of defense is chemicals secreted by plants that does not cause any harm to their closely related species.

For these problems, see your book for a detailed explanation of epistasis in labs, and also for the x? table. You have crossed two black labs that are both BbEe genotypes, and the resulting litter consists of 15 black, 4 brown, and 6 yellow labs. You conduct a x² test of the null hypothesis that the offspring match the expected ratios for recessive epistasis, and any differences are due to chance. The x value you calculate is 0.190. Part I: How many yellow labs do you expect? Answer to one decimal place (e.g., 0.8). 6.3 Part II: What are your degrees of freedom? Your answer should be a round number (e.g., 9). 2 Part II: Assuming a p-value cut-off of 0.05, what is the critical value that you will use to evaluate your hypothesis?
