Question
Chapter 20.3, Problem 6R
Summary Introduction
To explain: The function of cytokines secreted by helper T cells.
Introduction: T cells with CD4 markers respond to antigens displayed by class II MHC proteins. After activation, CD4 T cells produce two types of CD4 T cells: helper T (TH) cells, and memory TH cells.

- In a natural population of outbreeding plants, the variance of the total number of seeds per plant is 16. From the natural population, 20 plants are taken into the laboratory and developed into separate true-breeding lines by self- fertilization-with selection for high, low, or medium number of seeds-for 10 generations. The average variance in the tenth generation in each of the 20 sets is about equal and averages 5.8 across all the sets. Estimate the broad-sense heritability for seed number in this population.
