Question: A soybean mutant exhibiting a tan colored seed coat was recently identified. Crossing the mutant with the the wild-type,yellow-seeded soybean plant gave all yellow -seeded soybeans in the first generation, F1. Self-pollination of F1 provided in the second generation ,F2,814 yellow seeded and 201 tan-seeded plants.This pattern suggests a simple dominant-recessive model involving a single genetic mutation (3:1 expected ratio.)
A) what is the number of yellow seeded plants?
B) what is the observed chi sq value?
C) what is the critical chi sq value for alpha=.05?
D) what is the p-value for this chi sq test?
