The International Rice Research Institute in the Philippines develops new line of rice which combine high yields with resistance to disease and insects. The technique involves crossing different lines to get a new line which has the most advantageous combination of genes. Detailed genetic modeling is required. One project involved breeding new lines to resist the "brown plant hopper" (an insect): 374 lines were raised, with the results shown below.
Number of lines
All plants resistant 97
Mixed: some plants resistant, some susceptible 184
All plants susceptible 93
According to the IRRI model, the lines are independent: each line has a 25% chance to be resistant, a 50% chance to be mixed, and a 25% chance to be susceptible. Are the facts consistent with this model?
Group of answer choices
Using a
test for goodness of fit, P is less than 5% so the facts are NOT consistent with this model.
Using a
test of independence, P is less than 5% so the facts are NOT consistent with this model.
Using a
test for independence, P is much greater than 5% so the facts are consistent with this model.
