The function of the blood–brain barrier (BBB). Introduction: The BBB is a very selective barrier membrane, which creates a barrier between the blood and the extracellular fluid present in the central nervous system (CNS). This barrier is formed by the endothelial cells of the brain. It allows the movement of water, certain gases, and lipid soluble solute across the membrane by the means of passive and selective transport. Astrocytes, one of the neuroglia helps in the maintenance of the BBB.

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…
