In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).
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.
