A given neurotransmitter may be excitatory at one synapse and inhibitory at another synapse. If the given statement is true or false should be determined. Introduction: When an action potential spreads over the presynaptic terminal, it stimulates the release of a neurotransmitter from the neuron into a synaptic cleft. The concentration of the neurotransmitter then increases. So, due to an increase in action potential, there is an increase in the concentration of the neurotransmitter in the synaptic cleft.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
