Question
To measure the heritability of TTX resistance, we would need to
know the number of mutations that have occurred in the sodium-channel protein in Fig. 6 in the population of snakes we are studying.
measure resistance in a laboratory environment to remove all of the environmental effects.
estimate the slope of the relationship between the average resistance of the parents and the average resistance of the offspring.
test for a correlation between the level of toxicity in the newts and the level of resistance in the snakes.
A.know the number of mutations that have occurred in the sodium-channel protein in Fig. 6 in the population of snakes we are studying.
B.measure resistance in a laboratory environment to remove all of the environmental effects.
C.estimate the slope of the relationship between the average resistance of the parents and the average resistance of the offspring.
D.test for a correlation between the level of toxicity in the newts and the level of resistance in the snakes.
Explanation / Answer
We would need to test for correlation between level of toxicity in newts and level of resistance in snakes for measuring heritiblity of tetrodotoxin(TTX) resistance.
