The two fundamental physical properties of blood are its viscosity and osmolarity. Both are tightly regulated by homeostasis as survival measures. Blood viscosity determines flow through blood vessels. When blood viscosity rises, even thrice higher than normal as seen in primary polycythemia, flow in blood vessels gets sluggish and capillaries are plugged due to the highly viscous fluid. This decreases circulation and overloads the heart’s pumping function. Heart failure and stroke are a usual consequence of chronically high blood viscosity.

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…
