Chi-Square Value (X*). If the observed had equaled the expected, the value would
have been zero. Thus, a small X value indicates that the observed and expected
ratios are in close agreement.
Into a container put 270 corn kernels, 90 rice grains, 90 mongo seeds and 30 squash
seeds. Mix them together by stirring or shaking.
Supposing that we are crossing two double heterozygotic pea plants (AaBb x AaBb).
A=tall; a=Dwarf; B=Normal; b=wrinkled.
The four types of seeds represent the four possible phenotypes of the cross: Tall-
normal (Corn), Tall-wrinkled (Rice), Dwarf-normal (Mongo) and Dwarf-wrinkled
(Squash).
