The chi-square test is a statistical method used to determine whether there is a significant association between categorical variables. In this analysis, we are examining the F1 cross 1 between two traits: eye color (wild type red or white) and gender (male or female) in a population. Observed frequencies of each combination of traits have been provided.To calculate the chi-square statistic for the given data, we first need to set up the observed and expected frequencies in a contingency table. Based on the information provided, the table would look like this:the expected frequencies for each cell using the formula:Next, we'll calculate the chi-square statistic:ConclusionThe degree of freedom for a 2x2 table is 1.Now, you can compare the calculated chi-square statistic (χ2total2 ≈284.18) with the critical value from the chi-square distribution table with 1 degree of freedom to determine if the relationship is statistically significant.After performing the chi-square test, we obtained a total chi-square statistic value of approximately 284.18 with 1 degree of freedom. This value indicates a significant association between the traits of eye color and gender in the F1 cross 1 population. The calculated chi-square statistic surpasses the critical value from the chi-square distribution table, supporting the rejection of the null hypothesis that there is no relationship between the traits. This suggests that there is a statistically significant association between eye color and gender in the population under study.
