In corn (zea mays, purple kernels (r are dominant to yellow kernels (r. cobs from the offspring of a cross between a purple plant and yellow plant were used in a lab. a student counts 329 purple and 299 yellow kernels on one cob.

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

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and colour.
