marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.

Observed(o) Expected(e) (o-e) $(o-e)^2$ $(o-e)^2/e$

Green-melon plant 53 47 6 36 0.766

Yellow-melon plant 41 47 -6 36 0.766

Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.
