Introduction: Muscle contraction is usually stimulated by the motor neurons, which are known as somatic motor neurons. The contraction and the relaxation in muscles are brought by the actin and myosin filaments.

Expert Solution & Answer

Explanation of Solution

When the somatic motor neuron delivers electrochemical impulses, it stimulates the contraction of muscle fibres; it makes the synapses through which muscles are contracted and relaxed. The maximum amplitude of a summated muscle contraction is caused due to the persistence of stimulus. When the stimulus persists for a long time, the amplitude of the muscle contraction also gets maximized. This is due to the stimulation of muscles by the electrical or natural stimulation of the neurons. Tetanus is one of the examples that has maximum amplitude during muscle contraction.

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…
