Genes are segments of dna that determine the phenotype of an individual. pea colors can be yellow or green. when two plants that produce yellow peas were crossed, the offspring produced green peas. this is because the parents were __blank__ for pea color
1: heterozygous
2: homozygous dominant
3: homozygous recessive
because there were only two options of pea color, the plants' pea color is a case of
1: polygeneric traits
2: semiconservative replication
3: simple mendelian genetics

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.
