How the pineal gland function? Introduction: The pineal gland is present in thalamus region of the brain. It consists of neuroglia cells. This gland produces the melatonin hormone synthesized from serotonin. It controls the biological clock and circadian rhythms, due to the changes in the intensity of light during day and night. The impulse is transmitted in neurons and occurs in the form of feedback loop. The light is received by eyes, where the action potential is generated in the neurons and transfers the signal to hypothalamus region of the brain.

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…
