Question

In peas, a recessive trait causes the curling of leaves. A crossinvolving a plant with yellow pods and curling leaves wasmade to a wild-type plant with green pods and normal leaves. The F1plants were testcrossed and the following progeny obtained:
117 green pods, normal leaves 115 yellow pods, curling leaves 78 green pods, curling leaves 80 yellow pods normal leaves
a. what does the data suggest about the relationship betweenthe two genes?
b. Use a 2 test to determine ifyour conclusion is correct. (include properly worded null and alternative hypotheses, yourdegrees of freedom, and your calculated and table valuesof 2

Explanation / Answer

         The ratio of the above phenotypes i.e., is 117 greenpods,normal leaves: 115 yellow pods, curling leaves : 78 greenpods, curling leaves : 80 yellow pods , normal leaves is found tobe approx 1:1:1:1 . It is the dihybrid phenotypic ratio. Itindicates that the two pairs of factors are seggregating andassorting independently.
