When pink sweet peas were self-pollinated and the sceds were collected and sown, the following flower colors were obtained
red 34
pink 76
white 40
use a chi-squared test to determine whether these results are consistent with the hypothesis that pink flowers are heterozygous for a single pair we predict for our null hypothesis?
a. 9: 3: 4
b. 3: 1: 0
c. 1: 2: 1
d. 1: 4: 1

The proportions 1:2:1 are consistent with thenull hypothesis that the pink flowers are heterozygous for a single pair.

Option C

Explanation:

Chi square test is used to

(i)  Find significant difference in two or more than two proportions

(ii)The goodness of fit between the observed and expected frequency.                    

= 0.3266 + 0.0133 + 0.1666 = 0.506

5%  Critical value = 5.991

Degree of freedom = 2

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.
