In mountain rabbits, the EL-1 gene is located on chromosome 3. Eight alleles of this gene have been identified in the population. With respect to EL-1, what is the maximum number of genotypes in the progeny of a single cross between two mountain rabbits

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
