Answer:
X² = 1.44
Explanation:
Purple= R, and R is dominant on r
yellow =r,
As given, cross between a purple heterozygous corn plant (Rr) and a recessive yellow corn plant (rr)
yield offspring that display a 1:1 ratio between purple kernels and yellow kernels. Of the total kernels,
it would be expected that 279 would be purple and 279 would be yellow but here results are little differ. The chi-square value is
calculated as: the range of acceptable result should be 1.43-1.44.
Phenotype observed, expected, obs-exp, (obs-exp)2 (obs-exp)2/exp
Purple 329 314 15 225 0.72
Yellow 299 314 -15 225 0.72
X² = 1.44
