Answer:
See the answer below
Explanation:
The Chi-square (
) is calculated by the formula:
=
where O = observed frequency and E = expected frequency
A standard dihybrid cross is expected to give 9:3:3:1 phenotypic ratio.
Phenotype O E 
Round yellow 104 9/16 x 160 = 90
= 2.18
Round green 27 3/16 x 160 = 30
= 0.30
wringled yellow 27 3/16 x 160 = 30
= 0.30
wrinkled green 2 1/16 x 160 = 10
= 6.40
Total
value to two decimal places = 9.18
Degree of freedom = (n-1) = 4 -1 = 3
Critical
value at 95% probabillity level = 7.815
<em>Since the calculated </em>
<em> si more than the critical </em>
<em> value, </em><em>the null hypothesis is rejected. </em>
