1. you are studying a trait in corn that you believe exhibits mendelian inheritance. you count phenotypes and find that there are 375 of one phenotype and 125 of the other phenotype. when you perform a chi-square test, the chi-square value is zero. your conclusion based on this test is

this trait is inherited in a mendelilan fashion

none of the answers is correct

this trait exhibits codominance

this trait is not inherited in a mendelian fashion

this is a dihybrid cross

This trait is inherited in a Mendelian fashion.

Explanation:

Chi-square test is used to test the relationship b/w variables, on performing the chi-square test on traits of corn, value that we obtained was zero, it means that there is no relationship b/w two traits. So, the trait has been inherited independently in Mendelian fashion.

this trait is inherited in a Mendelian fashion

Explanation:

The chi-square test aims to verify whether the observed absolute frequency of a variable is significantly different from the expected absolute frequency distribution. Applies when one wants to study the dependency between two variables, through a double entry table or also known as a contingency table.

When chi square is calculated, the values of a table with constant numbers (called tabulated X) are compared with the result found in the chi square calculation. If the chi-squared value is zero, then there are no significant differences between the hypotheses. In the case of the above question, this would mean that the characteristic, studied in the above question, is inherited from Mendelian ways.
