Two genes are 11 map units apart on the same chromosome. A true-breeding BBss individual is crossed to a true-breeding bbSS individual. The F 1 offspring are mated to bbss individuals. If this testcross produces 1000 offspring, how many of them would you expect to be BbSs ?

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.

i believe it would be c: tons.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
