A cross was made between two strains of plants that are agriculturally important. One strain was disease-resistant but herbicide

-sensitive; the other strain was disease-sensitive but herbicide- resistant. A plant breeder crossed the two plants and then allowed the F1 generation to self- fertilize. The following data were obtained:
F1 generation: All offspring are disease-sensitive and herbicide-resistant
F2 generation: 157 disease-sensitive, herbicide-resistant
57 disease-sensitive, herbicide-sensitive
54 disease-resistant, herbicide-resistant
20 disease-resistant, herbicide-sensitive
Total: 288 Formulate a hypothesis that you think is consistent with the observed data. Test the goodness of fit between the data and your hypothesis using a chi square test. Explain what the chi square results mean.

hodyreva [135]

Answer:

<u>ion channels</u>

Explanation:

The plasma membrane plays a critical role in regulating and maintaining ionic potential inside the cell, relative to ionic concentration present outside the cell. The ion channels are specific, in that they only recognize and allow particular ions to pass through and block the rest. Their opening and closing depends on the ionic potential during that time period.
