Question

You have performed a dihybrid cross of plants and got the following data: 206 purple tall, 65 white tall, 83 purple short, 30 white short. Perform a chi-square analysis to test the null hypothesis that purple coloring is dominant to white and tall height is dominant to short height.

Answer 1

tell me the method.......

Answer 2

The a chi-square of the experimental data is 4.32.

Chi-square

Observed data(o)

Purple tall=206

White tall=65

Purple short=83

White short=30

Total=384

Expected (e)

9 Purple tall=216

3 White tall=72

3 Purple short=72

1 White short=24

Chi-square

Purple tall=(206-216)²/216=0.46

White tall=(65-72)²/72=0.68

Purple short=(83-72)²/72=1.68

White short=(30-24)²/24=1.5

X²=0.46+0.68+1.68+1.5

X²=4.32

Inconclusion  a chi-square of the experimental data is 4.32.
