Question

A set of Mendelian crosses involving two traits is performed. The first cross is between a plant with green and wrinkled seeds and a plant with yellow and smooth seeds. The F1 all have yellow and smooth seeds. The 160 F2 have 5 plants with green and wrinkled seeds, 33 with green and smooth seeds, 37 with yellow and wrinkled seeds and 85 with yellow and smooth seeds. A chi-squared test on these data is done to evaluate how well the data fit a hypothesis of independent assortment. In what range below is the value of chi-squared?

Explanation / Answer

total=160 yellow and smooth seeds=85: 9/16*160= 90:85 yellow and wrinkled seeds= 37: 3/16*160= 30:37 green and smooth seeds=33: 3/16*160= 30:33 green and wrinkled seeds=5: 1/16*160= 10:5 Report Abuse
